The sum of absorption and transmission of light in a medium is equal to?
Correct answer: A. Incident light
- A. Incident light
- B. Reflected light
- C. Any of a or b
- D. None of these
Explanation
An incident ray is a rectilinear ray of light that strikes a surface, known as an incident ray on that spot(surface). The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The total light transmittance through a material is equal to the total incident light less the light that is absorbed and light that is scattered.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
