When light traveling in one medium strikes the boundary of another medium a part of it is sent back in the same medium, this is known as _:
Correct answer: A. Reflection
- A. Reflection
- B. Rarefraction
- C. Polarization
- D. Interference
Explanation
Reflection is the correct answer because it describes the bouncing back of light when it encounters a boundary between two different mediums. Rarefraction, polarization, and interference do not accurately describe this specific behavior of light at a medium boundary.

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.
