A stroboscope or strobe is an instrument that works on the phenomenon of stroboscopic effect. It creates a stop motion effect of a rotating object by flashing a high-intensity light on it. This appearance of a moving object to be stationary can be used to study rotating, oscillating or vibrating objects.

What is stroboscope explain its working?

A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. ... When a rotating or vibrating object is observed with the stroboscope at its vibration frequency (or a submultiple of it), it appears stationary.

Why is a stroboscope a good idea?

A stroboscope makes it easier to see patterns of wave behaviour with continuous ripples in a ripple tank, especially with ripples at higher frequencies. Beware of water on the laboratory floor. Make sure you have a sponge and bucket handy to mop up spills immediately.
