Question

reflection meaning in physics ​

Answer 1

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. Common examples include the reflection of light, sound and water waves. Reflection is observed with surface waves in bodies of water.

Answer 2

Explanation:

Reflection of light is the phenomenon of bouncing back of light in the same medium on striking the surface of any object.

• The two laws of reflection are:

(i) the incident ray, the reflected ray and the normal (at the point of incidence), all lie in the same plane.

(ii) the angle of reflection (r) is always equal to the angle of incidence (i)

∠r = ∠i
