PHY 104 Reflection and Refraction of Light Objective Question
Take CBT

Question

What is the primary difference between diffuse reflection and specular reflection?
Options
A Diffuse reflection occurs only from transparent surfaces, while specular reflection occurs from opaque surfaces.
B In diffuse reflection, the law of reflection does not hold, unlike specular reflection.
C Specular reflection is when light reflects from a rough surface, causing rays to scatter in many directions.
D Diffuse reflection allows an eye to see reflected light at all angles, while specular reflection requires the eye to be in a specific position to see the reflection.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Page 11 explains the difference: 'With diffuse reflection, your eye sees reflected light at all angles. With specular reflection (from a mirror), your eye must be in the correct position.' Page 10 also states that in diffuse reflection, the law of reflection still holds, but the angle of incidence varies across the rough surface, leading to varied angles of reflection.

Hint

Consider how light reflects from a rough surface (like a wall) versus a smooth surface (like a mirror).
