Explanation:
Look at this website it gives you all the details! :)
On Earth, the period of a pendulum is given by:

where L is the length of the pendulum and

is the gravitational acceleration on Earth.
Similarly, the period of the same pendulum on Mars will be

where

is the gravitational acceleration on Mars.
Therefore, if we want to see how does the period of the pendulum on Mars change compared to the one on Earth, we can do the ratio between the two of them:

Therefore, the period of the pendulum on Mars will be 1.63 times the period on Earth.
The law of reflection states that "when a ray of light is reflected off a surface, the angle of incidence equals to the angle of reflection"
The angle of incidence is 62° means the angle of reflection is also 62°
