In a progressive longitudnal wave, the separation between a compression and immediate rarefaction is 2.4 m, if its speed is 360 m/s, the frequency is:

Sound from a flute and sound from a harmonica played by passing air through musical instrument, at same time and same distance from ear and traveling through same medium air, they differ in sounds due to difference in

A wire of uniform cross-section and length of 7 m is fixed between two rigid points. If a stationary wave is set in it and made to vibrate with one loop, the wave length of vibration will be:

The motion of the particles of a medium when a sound wave is passing through it is:

A source of wave produces 40 crests and 40 troughs in 0.4second.Find the frequency of the wave.

A swing has a time period of 1.4 seconds. The no. of oscillations made by it within 1 minute 24 seconds will be:

The distance between a compression and the next rarefaction of a longitudinal wave is

Arrange in increasing order - Speed of sound in steel, in distilled water, in sea water and in oxygen.

A transverse wave has a speed of 5040m/s,its frequency is 315 Hz,then the distance between a crest and immediate trough is

A bell vibrates 600 times within 3/2 seconds, its frequency and time period will be:
