Question

Is the light transmitted by a filter brighter than, less bright than, or the same brightness as the light that hits it? Explain your answer.​

Answer 1

Explanation:

The light transmitted by a filter is less bright than the light that hits it.

A filter only absorbs/removes part of the light that hits it. That means it removes some energy from the incident light. The remaining light carries less energy, so it must be less bright.
