In Same Direction And Of Same Frequency

Three waves producing displacement in the same direction of same frequency and of amplitudes 10etam, 4etam" and "7eta m arrive at a point with successive phase difference of pi//2 . The amplitude of the resultant wave is :--

In Same Direction But Are Of Different Frequencies

Consider two sound sources S_1" and "S_2 having same frequency 100 Hz and the observer O located between them as shown in the fig. All the three are moving with same velocity in same direction. The beat frequency of the observer is

A and B are two conductors carrying a current i in the same direction x and y are two electron beams moving in the same direction. There will be

A and B are two conductors carrying a current i in the same direction x and y are two electron beams moving in the same direction. Then

Two waves are propagating with same amplitude and nearly same frequency in opposite direction, they result in

Two particles execute S.H.M. along the same line at the same frequency. They move in opposite direction at the mean position. The phase difference will be :

In the production of beats by two waves of same amplitude and nearly same frequency, the maximum intensity to each of the constituent waves is

Two vibrating strings of same material stretched under same tension and vibrating with same frequency in the same overtone have radii 2r and r. Then the ratio of their lengths is:
