To know that sound can be reflected, refracted, diffracted, and produces interference effects.
Know that sound is a wave because it can be reflected and refracted as with particles, diffraction and interference only occur with waves

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
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.
12. Sounds travel through 3 media.
- Sound travels through the solid the fastest
(energy passed through closely packed particles)
- Sound travels through the gases the
slowest.
13. What is an echo?
Echo are sound waves that are reflected
back.
(When the sound wave hits a flat, firm
surface)
14.
15. How can echo or noise be
reduced?
By covering the room with soft, thick, uneven
material.
Wall paddingFloor foam Wood panels Wall art
16. How does covering rooms with the above
materials help?
When a sound wave hits the material the
sound is absorbed (changes to thermal energy).
Absorption:
Transfer of energy when
a wave disappears into a
surface.
20. Is there a difference between pitch and
frequency?
YES!!!
Pitch is the way our ears hear sound.
(The way we hear sound is related to the
number of peaks BUT, they are not the
same thing)
21. How to change pitch?
High pitch
Short guitar string
Vibrates fast
causing high pitch
23. If you are standing still the sound waves will
sound normal
24. If the source of sound is moving towards
you, you will hear more vibrations.
So the sound
you are
hearing
becomes high
pitched.
25. If the source of sound is moving away from
you, you will hear less vibrations.
So the sound you are hearing
becomes low pitched.
26. When sound frequency changes due to
moving towards or away from the sound.
The Doppler
effect.
27.
28. When you are TALKING the sound waves
will look like this
When you are SCREAMING the sound waves
will look like this
When you are WHISPERING the sound
waves will look like this
29. Amplitude
How dense is the air during compressions
and rarefactions.
Units:
Decibels (dB)
