A sound signal of 128 vibrations per second has a wavelength of 2.7m. Calculate the speed with which the wave travels.

A certain sound has a frequency of 256 hertz and a wavelength of 1.3 m. (a) Calculate the speed with which this sound travels. (b)What difference would be felt by a listener between the above sound and another sound travelling at the same speed, but of wavelength 2.6 m?

A tuning fork of frequency 170 Hz produces sound wave of wavelength 2m. Calculate speed of sound.

An electromagnetic wave has a frequency of 500 MHz and a wavelength of 60 cm. (a) Calculate the speed of the wave. (b) Name the medium through which it is travelling.

Derive the relation between velocity, frequency and wavelength of a wave. A certain sound waves in air has a speed 340 m//s and wavelength 1.7m. For this wave calculate the frequency and time period.

Sound waves produced by two vibrators have the same wavelength in two different gases. The speed of the waves in the two gases are 420 m/s and 400 m/s. The vibrators, when sounded together produce 8 beats/second. The wavelength in the two gases will be

A tuning fork makes 256 vibrations per second in air. When the speed of sound is 330 m//s , the wavelength of the note emitted is :
