Question

diffrence between REFLECTION and REFRACTION​

Answer 1

Answer:

Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.

Answer 2

in refraction light rays enter from one medium to another and deviate from its path
