Light always travels in straight lines. It comes into the periscope, gets reflected once through 90 degrees by a mirror placed at an angle, then is reflected back through 90 degrees again by a second mirror. Sometimes lenses are also used to magnify the image.

A ray of light can travel in any direction, so an infinite number.
Light rays travel in a straight line unless they are refracted or reflected by a medium. This straight path is known as rectilinear propagation. Light rays can also be bent when passing through different mediums with varying optical densities.
A straight beam of light is called a ray of light. Rays of light travel in a straight line from their source until they are interrupted or reflected by a surface.
When a ray of light is shone at a glass block, it will refract (bend) as it enters the glass due to the change in the speed of light in the material. The light will then travel through the glass block, possibly reflecting off the surfaces inside, and refract again as it exits the block.

All electromagnetic waves travel at the speed of light. How far they travel depends on when or whether they hit an object that they cannot pass through.
very carefully
Light ray and gamma ray both travel in a straight line.
since light wave is electromagnetic wave and is able to travel through vacuum. eg.x-ray gamma ray radio waves etc hence due to the electromagnetic properties of visible light it does not required medium
Light is a wave that travels through space across matter. The same way that waves travel from the center of a pond to the edges when you toss a stone in it.
incident ray =reflected ray why?

No.
You could try becoming a ray of light.
sometimes they get pulled over by the light police and given a ticket
