Why are sound waves called mechanical waves?
Fill in the blank.
The pitch of a sound depends on its ________.
Draw a displacement-distance graph of a wave and mark on it, the amplitude of wave by the letter 'a' and wavelength of wave by the letter λ.
An observer sitting in line of two tanks watches the flashes of two tanks firing at each other at the same time, but he hears the sounds of two shots 2s and 3.5s after seeing the flashes. If distance between the two tanks is 510m, find the speed of sound.
The speed of sound is more in hydrogen than in nitrogen. Is this statement true? Give a reason for your answer.
A continuous progressive transverse wave of frequency 8 Hz moves across the surface of a ripple tank
With reference to the frequency, describe the movement of water on the surface
A sound wave of wavelength 1/3 m has a frequency 996 Hz. Keeping the medium same, if frequency changes to 1328 Hz. Calculate
- velcoity of sound
- new wavelength.
Sound is a ______ wave and needs a material medium to travel.
Suppose that a sound wave and a light wave have the same frequency, then which one has a longer wavelength?
Vibrations in a body produce ______.
