Questions and Answers
Why do shadows form when light interacts with an opaque object?
Why do shadows form when light interacts with an opaque object?
- The opaque object reflects all the light away from the area behind it.
- The opaque object blocks the straight-line path of light, preventing it from reaching the area behind it. (correct)
- The opaque object absorbs all the light, creating a dark void.
- Light bends around the opaque object, creating an area of low illumination.
A light ray strikes a smooth surface at an angle of 30 degrees relative to the normal. What is the angle of reflection?

- 90 degrees
- 60 degrees
- 30 degrees (correct)
- 0 degrees
How does irregular reflection differ from regular reflection?
How does irregular reflection differ from regular reflection?
- Irregular reflection occurs on smooth surfaces, while regular reflection occurs on rough surfaces.
- Irregular reflection scatters light in many directions, while regular reflection reflects light in a uniform direction. (correct)
- Irregular reflection obeys the laws of reflection, while regular reflection does not.
- Irregular reflection produces clearer images than regular reflection.
