Waves- Total Internal Reflection

Question 1

What is the formula for the refractive index of a material?

Answer 1

speed of light in a vacuum(300,000,000m/s) divided by speed of slight in the material.

Question 2

What does the energy equal?

Answer 2

constant * frequency

Question 3

What is the formula for wave speed?

Answer 3

Wavelength * frequency

Question 4

What is the formula for wavelength?

Answer 4

Wave speed / frequency

Question 5

What is the formula for frequency?

Answer 5

Wavespeed / wavelength

Question 6

When does total internal reflection occur?

Answer 6

When the angle of incidence is larger than the critical angle

Question 7

What is total internal reflection?

Answer 7

When light is reflected back into the material as a result of the critical angle being smaller than the angle of incidence.

Question 8

What is a critical angle?

Answer 8

The angle in which light is beamed across a boundary.

Question 9

What is refraction?

Answer 9

When light travels from 1 medium to another which both have different densities.

Question 10

What is reflection?

Answer 10

When light bounces off a material.
