Light travels in a straight line and can be reflected, refracted, or absorbed when it hits different materials and surfaces. Reflection occurs when light bounces off a surface like a mirror, following the laws of reflection. Refraction is when light changes direction as it passes from one medium to another, like from air to water. Lenses and curved mirrors can form real or virtual images by refracting or reflecting light rays. Prisms disperse white light into a spectrum due to refraction, demonstrating that light is made of different colors.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. WHAT IS LIGHT?
• Light is a radiation or a form
of energy that our eyes can
detect. Light enables us to
view our surroundings.
• Light travels from one place
to another in a straight line.
3. DOES LIGHT TRAVEL IN
STRAIGHTLINE?
• The path of light gets blocked when an
object covers the source of light.
• This is illustrated by trying to see the
flame of a candle using a straight pipe and
then with a bent pipe.
• This proves that light travels in a straight
line.
5. REFLECTION
• When light is incident on a certain
surface, it either gets
reflected or bounces back.
• Such surfaces are really well polished
and act like a mirror. The
phenomenon of light bouncing off
surfaces is called reflection.
• A mirror that has a plane surface is
called a Plane Mirror.
• A mirror that is curved, it either
bulges in or out, is called a Curved
Mirror.
6. WHAT IS AN IMAGE?
• As a mirror reflects light, an image of the
object that is in front of the mirror is
formed on it.
• The image of an object can be defined as
the impression of the object created by
the light on the mirror.
• The distance between the image and the
mirror, and the object and the mirror
always remain the same.
• If we increase or decrease the distance
between the object and the mirror, the
distance between the image and the
mirror also increases or decreases,
respectively.
7. LEFT-RIGHT INVERSIONOF
THE IMAGE
• The image formed by the mirror is always
left-right inverted.
• This means that the right side of the
object appears as the left side of the
image, and the left side of the object
appears at the right side of the image.
9. • Incident Ray - The light ray that falls on the reflecting surface is called
an Incident Ray.
• Reflected Ray - The light ray that gets reflected back from a reflecting
surface is called a Reflected Ray.
• Normal - It is a line that is perpendicular to the reflected plane at the point
of incidence of Incident Ray.
11. TYPES OF REFLECTION
• Diffused Reflection or
Irregular Reflection -->
• Regular Reflection -->
12. SPHERICAL
MIRRORS
• A spherical mirror (or curved mirror) is a mirror which
has the shape of a piece cut out of a spherical surface.
• They are of 2 types: Concave and Convex.
13. REALIMAGEAND VIRTUALIMAGE
Real Image Virtual Image
The real image is formed when
the light rays reflect and meet at
the same point.
A virtual image is formed when
light rays reflect and diverge from
the same point.
It can be viewed on a screen. It cannot be viewed on the screen.
It is always inverted. It is always erect.
Formed by Concave mirror
Formed by Convex, Concave and
Plane Mirrors
14.
15. THE IMAGE FORMED BY A
CONCAVE MIRROR
• It can either be real or virtual.
• It can either be inverted or erect.
• It can have the same size as that of
the object, a larger size that of the
object or smaller size than that of
the object.
16. THE IMAGE FORMED BY A
CONVEX MIRROR
• It is always virtual.
• It is always upright (erect).
• It is smaller in size as that of the object.
17. APPLICATION OF CONCAVE
MIRRORS
• Satellite dishes use a concave mirror to
gather all the signals and reflect them on a
certain point.
• Dentists use a concave mirror to reflect light
on a particular tooth.
• Shaving Mirrors are concave in shape.
• Headlights of a car have a concave mirror so
that we can reflect back light straight on the
path.
• Torches also use concave Mirrors.
18. APPLICATIONOF
CONVEX MIRRORS
• The rear view mirrors are
convex mirrors as they provide
a wider view of the road
behind.
• Security mirrors near an ATM
are convex so that the user can
detect easily if anyone else is
watching from behind or not.
19. LENSES
A lens is a part of a reflecting material like glass or plastic but curved from
both sides. Lenses are unlike mirrors that have a reflecting surface only on one
side. Depending upon its shape a lens can be categorized as:
• ConvexLens - A Convex Lens is curved outwards. It is thicker in the centre
and narrows down at the edges. It merges the light rays passing through it at
a certain point. Therefore, it is also called a Converging Lens.
• ConcaveLens - A Concave Lens is curved inwards. It has wider edges and a
thinner centre. It reflects back the light that travels through it in different
directions. Therefore, it is also called a DivergingLens.
21. IMAGES FORMED BY CONVEX AND CONCAVE LENSES
A Convex lens forms an image that is:
• real
• inverted
• the image is large and appears close to the lens
A Concave lens forms an image that is:
• virtual
• erect
• small and appears far away
24. REFRACTION
• The bending of the path of light when
it moves from one medium to another
is known as refraction.
• The object we see after refraction is
called the apparent object.
• There exists some displacement
between the apparent and actual
object.
25. WHAT IS A
RAINBOW?
• A rainbow is a natural phenomenon
in which the light rays of the sun are
reflected and refracted by the water
droplets present in the atmosphere.
• A rainbow appears as an arc on the
sky that contains a band of seven
colors – Red, orange, yellow, green,
blue, indigo and violet.
26. RAINBOW
The white light of the sun contains
seven colored lights in it that
separate out due to refraction
(called a Spectrum of Lights). This
spectrum of white light can be seen
in the following:
• Rainbows
• Soap bubbles
• Surface of a CD
• Prisms
27. DISPERSIONOF
WHITE LIGHT
THROUGH PRISM
• Sunlight may appear as white but in fact,
is made up of seven component colors.
This can be observed when a beam of
sunlight is passed through a triangular
prism or when light falls on a compact
disk (CD).
• The seven colors that appear are violet,
indigo, blue, green, yellow, orange and
red. These are also the colors of a
rainbow we see after a rainfall.
• The splitting of white light into its
component colors is called dispersion.
28. NEWTON'S DISC
• The Newton’s disc can be obtained
by dividing a disk into 7 partitions
and painting each of them with the
seven colors of the rainbow.
• When the disc is rotated at a fast
pace in daylight all the colors tend
to mix together and the disc appears
whitish in color.
