Question 1.
What happens to light as it passes through a prism?
Show hintHide hint
Consider how angles relate to mediums.
Question 2.
Define the angle of deviation.
Show hintHide hint
Think about the path of light through the prism.
3Question 3.
What does an increase in the angle of incidence cause when light enters a prism?
- It decreases the angle of refraction
- It increases the angle of deviation
- It has no effect
Show hintHide hint
Think about how light behaves when it enters different mediums.
4Question 4.
True or False: The angle of minimum deviation always occurs when the light ray is parallel to the base of the prism.
- True
- False
Show hintHide hint
Consider how the light travels through the prism.
Question 5.
A prism has an angle of 45 degrees and a minimum deviation of 25 degrees. Calculate the refractive index of the prism material.
Show hintHide hint
Remember to convert angles into radians if necessary during calculations.
Question 6.
In an experiment, the angle of incidence is 30 degrees, and the angle of refraction is measured at 15 degrees. What is the refractive index of the medium?
Show hintHide hint
Look at how Snell’s law provides a way to calculate refractive indexes.
