D ,for lenses only​

Answer 1

Answer:

B, for mirrors and lens

Explanation:

• For rough surfaces, the law of reflection remains valid. It predicts that rays incident at slightly different points on the surface are reflected in completely different directions, because the normal to a rough surface varies in direction very strongly from point to point on the surface.
• In the reflection of light, the angle of incidence is equal to the angle of reflection, measured from the normal (the line perpendicular to the point of impact). According to the law of reflection, images are reflected from a smooth surface, such as a mirror, at the same angle (θ2) as the incidence angle (θ1).
