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
0.1
0.2
0.3
0.5
Solution
Beat frequency $=\mathrm{f}_2-\mathrm{f}_1=340-335=5 \mathrm{~Hz}$ Time interval between two maxima formed $=\frac{1}{5}=0.2 \mathrm{~s}$
