What does transmission of light involve?

Transmission of light involves the process where light travels through an object and continues on its path without being absorbed or significantly changed. This phenomenon occurs when light passes from one medium to another, such as from air into glass or water, allowing the light to maintain its energy and direction as it proceeds.

When discussing the other options: absorption refers to light being taken in by the material instead of passing through, scattering involves the light being diverted in multiple directions rather than maintaining a straight path, and reflection pertains to light bouncing off surfaces instead of transmitting through them. Therefore, the correct answer emphasizes the continuity of light travel through a medium, which is essential in understanding how various materials interact with light.
