The minimum angular speed.
Answer to Problem 14P
The answer is
Explanation of Solution
Given data:
Distance,
The Mirror has 8 sides,
Formula used:
It is known that:
Where,
Calculation:
Get the time that is taken by the light to reach from one mirror to the observer,
Since, each side of the mirror takes up
Therefore, the minimum angular speed at which the mirror rotate:
Conclusion: The required angular speed is
