Question

1. what happens when parallel light waves strike a rough, uneven surface? (1 point) they vibrate in one direction. they bend at an angle. they reflect in many different directions. they reflect in the same direction.

Explanation:

When parallel light waves strike a rough, uneven surface, it is a case of diffuse reflection. In diffuse reflection, the light scatters in many different directions because the surface is not smooth. For example, light hitting a piece of paper (a rough surface) scatters in various directions. The first option about vibration in one direction is related to polarized light (not reflection). The second option about bending at an angle is refraction (when light moves from one medium to another). The fourth option is for specular reflection (smooth surface like a mirror).

Answer:

They reflect in many different directions.
