Waves Set 2

The velocity of waves in a string fixed at both ends is The string forms standing waves with nodes apart. The frequency of vibration of the string in is

A spherical source of power and frequency is emitting sound waves. The intensity of waves at a distance is

The equation of a cylindrical progressive wave is

The sound carried by air from a sitar to a listener is a wave of the following type

The line of a sight of a jet plane makes an angle of with the vertical, and the sound appears to be coming from over the head of the observer. The speed of jet plane is (taking speed of sound waves to be v)

A 20 cm long string, having a mass of 1.0 g, is fixed at both the ends. The tension in the string is 0.5 N. the string is set into vibration using an external vibrator of frequency 100 Hz. Find the separation (in cm) between the successive nodes on the string

When two sinusoidal waves moving at right angles to each other superimpose, they produce

Two stretched strings of same material are vibrating under same tension in fundamental mode. The ratio of their frequencies is 1 : 2 and ratio of the length of the vibrating segments is 1 : 4. Then the ratio of the radii of the strings is

Two tuning fork of frequency and produces n beats per second. If and n are known, may be given by

If the amplitude of sound is doubled and the frequency reduced to one-fourth, the intensity of sound at the same point will be
