Question 1.
What is the law of reflection?
Show hintHide hint
Think about how angles behave when light reflects from a surface.
Question 2.
Define a wavefront.
Show hintHide hint
Consider how waves spread out in the medium.
3Question 3.
What does Huygens' principle state?
- All points on a wavefront are sources of secondary waves.
- Light waves cannot reflect off curved surfaces.
- The speed of light changes upon reflection.
Show hintHide hint
Consider how waves form and interact.
4Question 4.
True or False: The angle of incidence is always equal to the angle of reflection.
- True
- False
Show hintHide hint
Reflect on how light behaves when striking a surface.
Question 5.
If a plane wave strikes a mirror at an angle of 30°, what is the angle of reflection?
Show hintHide hint
Use the law of reflection directly.
Question 6.
A wavefront approaching a reflective barrier forms an angle of incidence of 45°. Describe the behavior and characteristics of the reflection.
Show hintHide hint
Visualize how equal angles maintain the law of reflection.
