Final answer:
Light interacts with mediums in four ways: reflection, refraction, absorption, and transmission.
Step-by-step explanation:
Light interacts with mediums in several ways. The four primary interactions are reflection, refraction, absorption, and transmission.
Reflection occurs when a light wave bounces off a material, such as a mirror.
Refraction happens when light waves change speed and direction as they pass from one medium to another, like when light passes through a lens.
Absorption occurs when a material captures the energy of a light wave. For example, black objects absorb most of the light that hits them.
Transmission occurs when a light wave travels through a material, like when light passes through glass.
