Characteristics of Vibrations

Define Frequency.

How to find wavelength of a wave?

The speed of a wave in a medium is $760 {\mathrm{ms}}^{-1}$.If $3600$ waves are passing through a point in the medium in $2$ minutes then its wavelength is 

The given graph shows the displacement versus time relation for a disturbance travelling with velocity $1500 \mathrm{m}/\mathrm{s}$. The wavelength of the disturbance will be

If the speed of wave is $350 \mathrm{m}/\mathrm{s}$ and its wavelength is $100 \mathrm{cm}$ then the frequency of the wave will be

When sound is refracted from air to water, which of the following will remain unchanged?

For the wave shown in figure, calculate the frequency and wave length of the wave if its speed is 320 ms–1.

What are the characteristics of wave. A sound wave travels at a speed of 340m/s. If its wavelength is 2cm, what is the frequency of the wave in $\mathrm{HZ}$?

A sound wave travels at a speed of 340m/s. If its wavelength is 2cm, what is the frequency of the wave in Hz? Will it be in the audible range?

The frequency of radio waves from a certain radio station is $600 \mathrm{KHz}$. Its wavelength is

A low note has a time period of $0.0125 \mathrm{s}$. What is its frequency?

The maximum displacement of the particle from its mean position is known as:

The distance between two consecutive compressions or rarefactions is called _____.

Loudness of a sound increases when amplitude of sound decreases.

When the amplitude of vibrations increases, its _____(pitch/loudness) increases.

The frequency of a source of sound is $100$ $\mathrm{Hz}$. How many times does it vibrate in a minute?

A source of wave produces $20$ crests and $20$ troughs in $0.2$ $\mathrm{s}$. The distance between a crest and next trough is $50$ $\mathrm{cm}$. Find the time period of the wave.

A source of wave produces $20$ crests and $20$ troughs in $0.2$ $\mathrm{s}$. The distance between a crest and next trough is $50$ $\mathrm{cm}$. Find the frequency.
