Beats

If the two waves of same amplitude, having frequencies 340 Hz and 335 Hz, are moving in same direction, then the time interval between two successive maxima formed (in second) is

Show answer and solution

Answer: (b)

Beat frequency $= 340 - 335 = 5\text{ Hz}$
Interval between successive maxima $= \frac{1}{5} = 0.2\text{ s}$
So the answer is (b) 0.2.
