Question

How does the 2 reflections obey the law of reflection?

Answer 1

Hint: Reflection is that the change in direction of a wave front at an interface between two different media in order that the wave front returns into the medium from which it originated. Common examples include the reflection of sunshine, sound and water waves.

Complete answer:
All reflected light obeys the connection that the angle of incidence equals the angle of reflection. Even as images are reflected from the surface of a mirror, light reflected from a smooth water surface also produces a transparent image. We call the reflection from a smooth, mirror-like surface specular.
When the surface of water is wind-blown and irregular, the rays of sunshine are reflected in many directions. The law of reflection remains obeyed, but the incident rays strike different regions which are inclined at different angles to every other.
Consequently, the outgoing rays are reflected at many various angles and therefore the image is disrupted. Reflection from such a rough surface is named diffuse reflection and appears matte.
The laws of reflection are obeyed in the least interfaces. The quantity of reflected light at the interface depends on the differences in refraction between the 2 adjoining materials.

Note:
The incident ray, the reflected ray and therefore the normal to the reflection surface at the purpose of the incidence dwell an equivalent plane. The angle which the incident ray makes with the traditional is adequate to the angle which the reflected ray makes to an equivalent normal.
