Physics M.C.Q (1 Marks)

Instead of pulling a stretched string from the middle point if one of its end is touched at the middle point and is pulled at distance of 1/4th then the frequency of vibration is higher than that of the first wave.

The node point in stationary wave:

If the length of a stretched string is doubled and the tension is four times then new frequency will be times of old frequency.

A tube with both open end its fundamental frequency is n. If half of tube is dipped in water vertically the fundamental frequency of air column.

When temperature increase then frequency of organ pipe.

The fundamental frequency is n of both open end of argon pipe. Keep in vertical and dip in water half length of tubes. So it will full with half water the fundamental frequency of air column.

If the ratio of same thickness's wire densities is 1 : 2. If we keep same mass then ratio of same length frequency will be :

Third harmonic frequency in open argonpipe:

Maximum speed of sound is:

Velocity of transverse wave in stretched string doesn't depend on:

Second harmonic of open pipe is:

Density of antinodes in stationary wave is:

Maximum amplitude point in stationary wave is called-

Minimum amplitude point in stationary waves is called:

Which types of vibration generated in gitar's wire:

The fundamental frequency of air is 300 Hz in a open air argon pipe. The first overtone of open pipe is whose first overtone of other close argon pipe length of close argon pipe is (v = 336m / s):

If the speed of sound in air is 332 m/s and length of a close pipe is 1 meter. The fundamental frequency of generated sound from pipe.
