Mirror Reflection

APPH12-Y$EJVG

A bright light bulb is turned on and held near a smooth bathroom mirror. The reflection of the light bulb is observed in the mirror.

Which of the following is most likely true regarding the light striking the mirror?

A

All of the light from the light bulb is reflected off the mirror. This is evident by the fact the light bulb's reflection is as bright and as clear as the light bulb itself.

B

Not all of the light from the light bulb is reflected by the mirror. Some of the light is absorbed as evident by touching the mirror and feeling the mirror has increased in temperature.

C

Not all of the light from the light bulb is reflected by the mirror. Some of the light is absorbed as evident by noticing the reflected image is inverted. The left side of the light bulb appears as the right side of the light bulb in the reflection and vice versa.

D

Not all of the light from the light bulb is reflected by the mirror. Some of the light is absorbed as evident by noticing the reflected image is dimmer and less clear than the actual light bulb.
