sound wave in air strikes the surface of a lake and penetrates into water. If speed of sound in water is

1500\,\,\mathrm{m}{\mathrm{s}^{ - 1}}

, the frequency and wavelength of waves in water are

View answer and explanation

Correct option: B

1000\,\,\mathrm{ }Hz,\mathrm{ }1.5\,\,m

Option B (1000 Hz, 1.5 m) is correct because the frequency remains the same when a wave travels from one medium to another, and the wavelength changes according to the change in speed.

is the distance from the source) One metre long tube, closed at both ends, is lying horizontally. A mercury column of length 0.1m is filled in its middle and in rest two parts air is filled at atmospheric pressure. When tube is turned to vertical position, then displacement of mercury will be (standard pressure = 0.76 m of Hg) A tuning fork produces waves in a medium. If the temperature of the medium changes, then which of the following will change In a stationary wave all the particles A SONAR system fixed in a submarine operates at a frequency

40.0 \mathrm{kHz}

. An enemy submarine moves towards the SONAR with a speed of

360 \mathrm{~km} / \mathrm{h}

. What is the frequency of sound reflected by a submarine? Take the speed of sound in water to be

1450 \mathrm{~m} / \mathrm{s}

. A train moving at a speed of

220\,\,m{s^{ - 1}}

towards a stationary object, emits a sound of frequency 1000 Hz. Some of the sound reaching the object gets reflected back to the train as echo. The frequency of the echo as detected by the driver of the train is {speed of sound in air is
