Answer:
yes, it is true.
Explanation:
When a light ray falls on a highly smooth and polished surface, it bounces back into the same medium. This phenomenon is called reflection of light.
There are two laws of reflection.
1. The angle of incidence is equal to the angle of reflection.
2. Incident ray, reflected ray and the normal all lie in the same plane.

Answer:
Frequency, f = 1 unit
Explanation:
It is given that,
Period of the wave, T = 1 unit
We need to find the frequency of the wave. There exist an inverse relationship between period and the frequency of the wave. It is given by :
Or
f = 1 unit
So, the frequency of the wave is 1 unit. Hence, this is the required solution.
