Question

If the vibrator in a ripple tank strikes the water surface 40 times a second what is the frequency of the wave produced?If the frequency of the vibrator is halved what happens to the frequency of the waves

Answer 1

Answer:

Since the vibrator in ripple tank strikes the water surface 40 times a second,

So the frequency of the wave produced is 40Hz(40 waves in a second)

If frequency of the vibrator is halved,the frequency of the waves produced will also be halved (i.e. 20Hz) since the frequency of the waves produced is directly related to the frequency of the source
