What process occurs when all of the energy from light waves is transferred to a medium?
a.
transparency
b.
refraction
c.
metamorphosis
d.
absorption

The right answer is D

When light spreads in a medium (air, water, glass ...), it interacts with it. The latter modifies the properties of light. He can change his speed, take energy from him (rarer, give him some).

The luminous intensity can decrease in the mediums. This is the phenomenon of absorption (example: sunglasses). It can also grow in amplifying media. These media are used in lasers.
