List the measures that you will take when designing a sound-proof room.
To detect the obstacles in their path, bats produce ______.
'Note' is a sound :
The speed of sound in air at 0°C is nearly :
The distance between three consecutive crests of wave is 60 cm. If the waves are produced at the rate of 180/ min, calculate:
- wavelength
- time period
- wave velocity.
The diagram given below shows a displacement distance graph of a wave. If the velocity of wave is 160 ms-1, calculate:
- wavelength
- frequency
- amplitude.
What is the value of sound of room temperature?
Draw a curve showing density or pressure variations with respect to distance for a disturbance produced by sound. Mark the position of compression and rarefaction on this curve. Also, define wavelengths and time periods using this curve.
