Question

define reflaction and refraction​

Answer 1

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

Answer:

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.

Refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

Explanation: not reflaction, it is reflection
