What is the phenomenon of bending of light?

Answer 1

There are two ways light can bend:

1. Refraction/Diffraction:

When light travels from one medium to another, such as air to water, the light slows down (or speeds back up depending upon which medium it is entering and leaving). This change in speed causes the light to bend. The reason light slows down is because the photons interact with particles in the medium. I show this in class by doing the following:

I walk from one end of the room to the other without stopping. That represents light going through a vacuum. Then I walk the same path, but this time I shake the hand of each student I pass. This represents light going through a medium such as air or water. Obviously it took me longer to do the second trip.

Diffraction is another way light can bend. It is due to light bending as it travels through a small hole or slit. It also occurs when it bends around a corner, but that amount of bending is very small. If you have ever been in a dark room, and the light is on in the hallway, no doubt you have noticed the light doesn't come in at a right angle from the door's opening. It bends at a small angle from the door's edge. That is diffraction.

2. Gravity:

Gravity can be thought of as the curvature of the fabric of spacetime. If you put a bowling ball on a trampoline, it will create an indention. The trampoline represents spacetime, and the bowling ball represents either a planet or the sun. Light travels in a straight line through the spacetime fabric, much like if you were to draw a straight line on the flat surface of the trampoline. However, if you were to draw that line through the indention of the trampoline, caused by the bowling ball, that line would curve. So, it isn't that gravity pulls on the light. The light is simply falling the contours of spacetime.

Answer 2

Generally a light bends when it travels from one medium to another this phenomenon is called refraction.
The basic reason is speed of light changes......bye.

Answer 3

refraction 99.9% of the times difraction and gravitation can also enter, with a long and fine water container put sugar on it do not mix just let it rest then point a laser to it, you will se the light bend

Answer 4

can be rfraction or diffraction coz in case of refraction light bends when it enters from a rarer/denser medium to a rarer /denser medium. but in case of diffration it bends about th sharp edges of an obstacle.

Answer 5

Refraction.

Answer 6

when light travels from one medium to another medium it bends and that is called Refraction of light.Good bye!!!

Answer 7

REFRACTION IS THE PHENOMENON DUE 2 WHICH LIGHT
BENDS WHILE TRAVELLING FROM ONE OPTICAL MEDIA 2 ANOTHER.IF THE LIGHT TRVELS FROM AN OPTICALLY REARER 2 AN OPTICALLY DENSER MEDIUM IT BENDS
TOWARDS THE NORMAL AND WHEN IT TRAVELS FROM AN
OPTICALLY DENSER TO AN OPTICALLY REARER MEDIUM
IT BENDS AWAY FROM THE NORMAL.

Answer 8

not the way you reported it. undemanding travels in a instantly line in area. in spite of the undeniable fact that, gravity warps area. Blackholes distort spacetime, which effectively causes undemanding to modify route, or "bend". lookup Einstein Ring.

Answer 9

it's called Refraction of light

Answer 10

refraction
