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. Common examples include the reflection of light, sound and water waves.

According to the law of reflection,

• The angle of incidence is equal to the angle of reflection.

So, if angle of incidence is 30 degree, then the angle of reflection will be also  30 degree.
