Question

. Atuning fork of frequency of 300 Hz and another
tuning fork of unknown frequency are vibrated
together. If they produce 10 beats in one second,
the time interval between two consecutive beats
1) 0.1s
2) 0.2 s
3)0.5 s
4)None
​

Answer 1

Answer:

0.1 s

Explanation:

Beats means the difference in frequency of two vibrating objects. As frequency is the number of vibrations in one second, if the beats frequency is 10, then the time interval between two consecutive beats should be the reciprocal of the beats frequency. Here, it is 1/10 = 0.1 S
