Optics and Light Behavior Quiz

What are the two main properties discussed at the beginning of the optics section?

• Reflection and diffraction

• Reflection and refraction

• Diffraction and interference

• Absorption and transmission

What does a higher index of refraction indicate about a medium?

• Light travels slower in the medium

• Light travels faster in the medium

• The medium is less dense

• The medium is a vacuum

What happens to a light beam when it enters a new medium?

• It accelerates

• It bends

• It remains unchanged

• It disappears

What is the relationship between the incident angle and the reflected angle?

• The incident angle is always larger

• They are unrelated

• The reflected angle is always larger

• They are always equal

How does the incident angle affect the amount of light reflected?

• A smaller incident angle increases reflection

• A larger incident angle increases reflection

• The incident angle has no effect on reflection

• A smaller incident angle decreases reflection
