Which of the following occurs as a light wave bends when it passes from one medium to another
a constructive interference
b destructive interference
c refraction
d reflection

Refraction is a phenomenon in which a light wave bends or changes its direction when passing through a medium with a refractive index different from the other medium.  

Being the refractive index is a number that describes how fast light propagates through a medium or material, and is defined as the relation between the speed of light in vacuum () and the speed of light in the second medium:

It is important to note that in this process, the wavelength may be modified because it depends on the medium, however, the refracted ray of light does not change its frequency.

are there options? cause you ain’t. real specific
