Stroboscope is used for the measurement of _________________?
Correct answer: D. Rpm of a flywheel
- A. Liquid level under pressure
- B. Frequency of light
- C. Depression of freezing point
- D. Rpm of a flywheel
Explanation
A stroboscope makes a rotating object appear stationary when the flashing frequency matches its rotational frequency, allowing its rpm to be determined. It is not used for measuring light frequency or liquid level.
