When light strikes the a material and most of the light is absorbed or reflected what optical must the material have?
true
Modes for propagating light along optical channels?
Angle of reflection
What are parts provide light in microscope?
Light in an optical microscope is either provided by light reflected off the mirror under the 'stage' - or by a battery/mains powered light bulb.
Is light bouncing off a mirror reflected or refracted?
Light bouncing off a mirror is reflected. Reflection is when the light bounces off a shiny surface back to your eye while refraction is when the light changes direction when passing from one medium to another medium of different optical density.
Is it true An optical fiber can make a light beam travel in a path that is curved or twisted?
Yes, that is true - and that is commonly used in modern technology, but especially to transmit information. Note that in an optic fiber, light travelling along the fiber is simply reflected back inside, if it reaches the borders.

How is light used in fiber optics?
Light enter the optical fibre, and is totally internally reflected all the way along.

true
Why doesn't light escape from the sides of an optical fiber?
optical fibres are made out of materials with high refractive index, this ensures that the light is always reflected back inside the fibre..
What are optical microphones?
Optical microphones are type of a microphone in which the movement of the microphone membrane is sensed optically. Usually there is a light source and photo-detectors to capture the light reflected back from the membrane.
Why is it necessary for amplifiers to be placed at regular intervals along an optical fiber when transmitting over long distances?
Some of the light injected by the optical transmitter is lost along the length of the fiber as the light travels. The optical receiver needs a minimum amount of light to function properly. Therefore optical repeaters must be installed at intervals along the path to keep the light level above the level needed by the last receiver.

What is the optical device that projects an enlarged version of an opaque object onto a screen by means of a reflected light?
This is known as an episcope.
What is an Optical Telescope for?
It is used to observe features of stars, planets, and other celestial objects by their visible light (generated or reflected).
Which types of electromagnetic waves can be used to send signals along optical fibers?
Only light is used to send signals along optical fibres. That's why this type of fibre is described as "optical". Fibres designed to conduct electrical signals are referred to as "wires".
