Refraction Of Light

Question 1

Optical fibre

Answer 1

A thin transparent glass tube that can transmit light even around corners

Question 2

Medium

Answer 2

A material that is being used or is undergoing a process

Question 3

Refraction

Answer 3

The bending of light rays as they pass between two different media

Question 4

Index of refraction

Answer 4

The amount by which a transparent medium decrease the speed of light is indicated by a number called the index of refraction

Question 5

Dispersion

Answer 5

The refraction of white light into separate wavelengths or colours

Question 6

Dispersion

Answer 6

The refraction of white light into separate wavelengths or colours

Question 7

Snells law

Answer 7

A formula that uses values for the index of refraction to calculate the new angle that the ray will take as a beam of light strikes the interface between 2 media

Question 8

Total internal reflection

Answer 8

When light reflects completely off the inside wall of a denser medium higher index of refraction rather than passing through the wall into less dense medium

Question 9

Mirage

Answer 9

An image of a distant object produced as light refracts through air of different densities
