Question

multiple choice question
the decrease in the intensity of light over distance, such as with increasing depth in water, is known as

○ attenuation
○ diffusion
○ radiation

Explanation:

Attenuation refers to the reduction in the intensity of a signal (such as light) as it travels through a medium. Diffusion is the spreading out of particles. Radiation is the emission of energy as electromagnetic waves or moving sub - atomic particles. In the context of light intensity decreasing with distance (like in water), the correct term is attenuation.

Answer:

attenuation
