Question

question 5 of 10

what is the difference between specular and diffuse reflection?

wave speed
surface smoothness
light color
wave frequency

Explanation:

Define specular and diffuse reflection

Specular reflection occurs on smooth surfaces.
Diffuse reflection occurs on rough surfaces.

Identify the key difference

The physical difference lies in surface smoothness.
Smooth surfaces reflect light in one direction.
Rough surfaces scatter light in many directions.

Evaluate the given options

Wave speed remains constant in the same medium.
Surface smoothness determines the type of reflection.
Light color relates to wavelength, not surface interaction.
Wave frequency does not change upon reflection.

Answer:

• Wave speed
• Surface smoothness (Correct answer)
• Light color
• Wave frequency
