A sounding source has a frequency of 256 Hz. If the temperature of air be `27^@C`, what is the wavelength of wavessent by the source? Velocity of sound in air at `0^@C`, = 331`m//s`.

At NTP, velocity of sound in air at 0^@C by Newton’s formula is

A bat emits ultrasonic sound of frequency 100 kHz. If this sound meets a water surface what is the wavelength of the transmitted sound in air and water respectively?

A source of sound has frequency 2000 Hz. If the speed of sound in air 340m//s , find the distance covered by sound when the source completes 400 vibrations.

A source and an observer move away from each other with a velocity of 10 m/s with respect to ground. If the observer finds the frequency of sound coming from the source as 1950 Hz , then actual frequency of the source is (velocity of sound in air = 340 m/s )

The tuning forks of frequencies 320 Hz and 340 Hz produce sound waves of wavelength differing by 6 cm in air. The velocity of sound in air is

The wavelength of a note is 3 m in air when the temperature is 17^@C . Find the wavelength of the same note in air 37^@C .

What is the fundamental frequency of vibration of an air column in a glass tube 30 cm long if. Both the ends of the tube are open? Velocity of sound in air = 360 m//s

A tuning fork has frequency 512 Hz. The number of vibrations of the fork in the time during which the sound from the tuning fork reaches 332 m in air are (velocity of sound in air is 332 m//s .)
