Sunlight shining through a clear window hits Jeremy's face while he does his homework. He uses a large wooden block to cover the window. What do the wooden block and the clear window demonstrate?

Question

A.
Visible light can be transmitted through all materials.
B.
Visible light can be completely absorbed by all materials.
C.
Visible light can be completely reflected by all materials.
D.
Visible light can be transmitted only through certain materials.

Answer 1

The scenario described demonstrates that sunlight can pass through a clear window, which allows light to reach Jeremy's face, while the wooden block blocks the light when placed in front of the window. This indicates that not all materials allow light to pass through.

The correct answer is: D. Visible light can be transmitted only through certain materials.
