Want this question answered?
refraction and reflection are similar because *they both have to do with waves*
Refraction ~ look to related link below .
none of the above
Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.
Perhaps you are confusing with "refraction"? Refraction means that when a wave goes from one substance to another (for example, from air to water), it changes its direction. This is related with the index of refraction in the different substances, i.e., the wave has a different speed in the different substances.

they the same

the refraction of light in water medium is 1.0003,glass 1.5,etc.

There will be refraction when light passes from one substance to the other (for example, from air to water), when the two substances have different indices of refraction, and when light passes the surface at an angle. In other cases, there is no refraction.
diffraction, reflection, refraction
Refraction occurs when light travels from one medium to another having different optical densities.
Refraction
They both cross the boundary from one medium to another.
