Question 1.
Define refraction.
Show hintHide hint
Think about how light behaves in different materials.
Question 2.
What is the angle of incidence?
Show hintHide hint
Look at the relationship of incident ray to the normal line.
3Question 3.
What is refraction?
- A change in color
- Bending of light
- An increase in temperature
Show hintHide hint
Think about how light appears in different environments.
4Question 4.
True or False: The incident ray, the refracted ray, and the normal all lie in the same plane.
- True
- False
Show hintHide hint
Visualize these elements together.
Question 5.
A person looks at a quarter submerged in a glass of water at an angle. If the quarter appears to be 45% larger than its actual size, calculate the angle of refraction using the formula for refractive index.
Show hintHide hint
Consider how the refractive index will influence the perceived size and angle.
Question 6.
Assuming light travels in a medium with a refractive index of 1.5, if the incident ray is at 30 degrees, what is the angle of refraction?
Show hintHide hint
You'll need to calculate the sine of both angles.
