Optics is the branch of physics that deals with light, including its interactions with matter and the construction of instruments that use or detect light. Optics describes the behavior of visible light, ultraviolet light, and infrared light. Many everyday devices use optical principles, including eyeglasses, cameras, and displays. Telescopes and microscopes are optical instruments that respectively collect light from distant astronomical objects and allow close examination of small samples. Atmospheric optics describes phenomena like rainbows and the blue color of the sky caused by the scattering of sunlight in Earth's atmosphere.
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy.

Microscopy is the technique of using microscopes to observe and analyze objects that are too small to be seen by the naked eye. Microscopes are instruments that magnify and resolve the details of objects, allowing scientists and researchers to study the structure, composition, and behavior of materials and specimens at a microscopic level

Eye microscopy and electron microscopy include differentiation and reflection. Retraction of magnetic fields/electron beams that interact with the image. As well as the scattering of scattered rays or other signals to create the image.
This procedure can be done by inserting a wide-field light sample or by scanning a fine beam over the sample. A microscopy scan probe involves. The interaction of the scanning probe with the surface of the object of interest.
Advances in microscopy transformed living things and exposed the field of histology. And so remain an important strategy for health and natural science.
X-ray microscopy is three-dimensional and unobtrusive. Allowing for repeated photographing of the same sample in situ or 4D subjects. And provides the ability to "see". The sample is readable before devoting it to advanced correction techniques.
The 3D X-ray microscope uses a computed tomography technique, rotating the sample. By 360 degrees and reconstructing images. CT is usually done with a flat panel display. The 3D X-ray microscope uses a series of objectives, e.g., from 4X to 40X, and can include a flat panel.
History of Microscopy
The field of the microscope dates back to at least the 17th century. Early mirrors, single-lens magnifying glasses with limited size. Back to the widespread use of eyeglasses in the 13th century. But the most advanced microscopes first appeared in Europe around 1620 Early.
Microscope doctors included Galileo Galilei, who was discovered in 1610. That he could turn off his telescope to see small objects nearby. And Cornelis Drebbel. Who may have invented the compact microscope in about 1620?
Antonie van Leeuwenhoek developed a simple magnifying microscope. In the 1670s and is often regarded as the first acclaimed microscopist and microbiologist.
Microscope Uses
to view bacteria, parasites, and a variety of human/animal cells
cellular process, cell division
DNA replication
tissue analysis
examining forensic evidence
studying the role of a protein within a cell
studying atomic structures
And in what way are bacteria able to infect human cells, then we use a microscope to study them all. Those studies are done at the micro-level.
We use a microscope to perform the kind of study that we cannot see with the naked eye.

2. Optics is the branch of physics which involves the
behaviour and properties of light, including its
interactions with matter and the construction of
instruments that use or detect it. Optics usually
describes the behaviour of visible, ultraviolet, and
infrared light. Because light is an electromagnetic
wave, other forms of electromagnetic radiation
such as X-rays, microwaves, and radio waves
exhibit similar properties
Introduction
3. Optics is part of everyday life. The ubiquity of visual
systems in biology indicates the central role optics
plays as the science of one of the five senses. Many
people benefit from eyeglasses or contact lenses, and
optics are integral to the functioning of many
consumer goods including cameras. Rainbows and
mirages are examples of optical phenomena. Optical
communication provides the backbone for both the
Internet and modern telephony
APPLICATION IN EVERY DAY LIFE
4. The human eye functions by focusing light onto an array of photoreceptor cells called
the retina, which covers the back of the eye. The focusing is accomplished by a series of
transparent media.

5. A telescope is an instrument that aids
in the observation of remote objects
by collecting electromagnetic
radiation (such as visible light). The
first known practical telescopes were
invented in the Netherlands at the
beginning of the 17th century, using
glass lenses. They found use in
terrestrial applications and
astronomy
Telescope
6. An optical telescope gathers and focuses light mainly
from the visible part of the electromagnetic spectrum
Optical telescopes increase the apparent angular size of
distant objects as well as their apparent brightness. In
order for the image to be
observed, photographed, studied, and sent to a
computer, telescopes work by employing one or more
curved optical elements, usually made from glass
lenses and/or mirrors, to gather light and other
electromagnetic radiation to bring that light or
radiation to a focal point. Optical telescopes are used
for astronomy and in many non-astronomical
instruments

7. A microscope is an instrument used to
see objects that are too small for the
naked eye. The science of investigating
small objects using such an instrument is
called microscopy. Microscopic means
invisible to the eye unless aided by a
microscope.
The most common type of microscope (and the
first invented) is the optical microscope. This is
an optical instrument containing one or more
lenses producing an enlarged image of a sample
placed in the focal plane. Optical microscopes
have refractive glass and occasionally of plastic
or quartz, to focus light into the eye or another
light detector.

8. The unique optical properties
of the atmosphere cause a
wide range of spectacular
optical phenomena. The blue
colour of the sky is a direct
result of scattering of blue
light. Because blue light is
scattered more easily than red
light, the sun takes on a
reddish hue when it is
observed through a thick
atmosphere, as during a
sunrise or sunset.
Atmospheric optics
9. A colourful sky is often due to scattering of light off particulates and pollution, as in
this photograph of a sunset during the October 2007 California wildfires
