About 150 years ago Armand Fizeau used a toothed wheel to measure the
The speed of the wheel after rotating in the order for the light to arrive back at the wheel and pass through the gap next to the one through which s first passed is to be determined.
Answer to Problem 51A
The angular speed is
Explanation of Solution
Given info:
Distance is 8Km
Formula used:
The angular distance is calculated as
Where
Calculation:
The round trip time period for the light =
Angular gap spacing,
The angular velocity of the light is
The angular velocity in revolution per minute is
Conclusion:
The angular speed is
