Waves And Sound...

If at a place, the speed of a sound wave of frequency 300 Hz is v, then the speed of another wave of frequency 150 Hz at the same place is

Bells are made of metal and not of wood, because

Ultrasonic, infrasonic and audible waves travel through a medium with speeds v_u, v_i and v_a, respectively. Which of the following relations holds true?

If the intensity ratio of two waves is 4 : 1, then the ratio of their amplitudes is

For each degree centigrade rise of temperature, the velocity of sound in air increases by

A string A has double the length, double the tension, double the diameter and double the density than string B. The ratio of their fundamental frequencies of vibration (n_A and n_B) is

The speed of sound is maximum in

Transverse waves are generated in uniform steel wires A and B by attaching their free ends to a vibrating source of frequency 500 Hz. The diameter of wire A is half that of wire B and the tension of wire A is half that of wire B. The velocities of waves in wire A and wire B are in the ratio

Velocity of sound in a gas is proportional to

The velocity of sound in air is not affected by changes in

Which of the following statements is correct?

The speed of a sound wave having a frequency 256 Hz compared with the speed of a sound wave having a frequency 512 Hz is

The loudness of sound depends upon

The shrillness (pitch) of a sound note depends upon

The sound of a lion is different from that of a mosquito because

The quality of a tone

It is possible to recognize a person by hearing his voice even if he is hidden behind a solid wall. This is due to the fact that his voice

The same note being played on a Sitar and a Veena differs in

In an orchestra, the musical sounds of different instruments are distinguished from one another on the basis of

Two identical strings are stretched at tensions T_A and T_B. A tuning fork is used to set them in vibration. If A vibrates in its fundamental mode and B in its second harmonic mode, which of the following relations holds true?
