Write true or false for a given statement.
Larger is the amplitude, feeble is the sound.
What is a longitudinal wave ?
Name the two characteristics of sound which differentiate two sounds from each other.
Why are the waves mentioned by you not audible to us?
When we change a feeble sound to a loud sound, we increase its :
Describe a simple experiment to determine the speed of sound in air. What approximation is made in the method described by you?
A cannon is fired at A (see diagram). An observer at B hears two sounds. The first sound is heard after 1 second and the second 3s after the observer sees the flash. (Velocity of sound = 340 ms−1)
(i) Why does the observer see the flash before he hears the sound?
(ii) Calculate the distance x between the observer and the wall.
A continuous progressive transverse wave of frequency 8 Hz moves across the surface of a ripple tank
If the wavelength of the transverse wave is 32 mm, calculate the speed with which wave travels across the surface of the water.
Suppose that a sound wave and a light wave have the same frequency, then which one has a longer wavelength?
