Waves Test - 6...

A boat at anchor is rocked by waves whose crests are 100 cm apart and whose velocity is 25 cm/sec. These waves reach the boat once every

A certain broadcasting station broadcasts at frequency of 12 Mega Hz. The wavelength of waves emitted is

There are three sources of sound of equal intensities with frequencies 400, 401 and 402 Hz. The number of beats per seconds is

The velocity of sound in gas in which two waves of wavelength 1.0 m and 0.01 m produces 4 beats/sec. is

A fork of unknown frequency when sounded with another fork of frequency 256 Hz produces 4 beats/sec. The first fork is loaded with wax. It again produces 4 beats/sec. When sounded together with the fork of 256 Hz frequency, then the frequency of first tuning fork is

When two or more waves traverse the same medium, the displacement of any element of the medium is the vector sum of the displacements due to each wave. This is known as
