Glare appears on a computer screen when light from the surroundings reflects off of the screen’s surface. Some computer screens have a special coating to reduce glare. Which best explains how the coating works?
Answer
A
The surface of the coating is rough, so light that shines on it gets scattered in many directions.
B
The coating bends light that passes through it and prevents the light from reaching the user’s eyes.
C
The surface of the coating allows light from the room to pass through but blocks the light from the screen.
D
The coating absorbs light that shines on it and prevents the light from reflecting.
Explanation
A rough surface scatters reflected light in many directions instead of reflecting it in a concentrated way toward the user’s eyes. That reduces the bright reflections perceived as glare. The coating does not need to block the screen’s own light or absorb all incoming light.
