Sound Test - 32...

A wave is moving in air with a velocity of 340 m/s. Calculate the wavelength if its frequency is 512 vibrations/ sec ?

Which is the quantity determines the loudness of a sound wave ?

Two sounds $A$ and $B$ are of the same amplitudes, same wave forms, but of frequencies $f$ and $2f$ respectively. Then:

A person standing symmetrically between two cliffs claps his hands and starts hearing series of echoes at intervals of 1 sec. If speed of sound in air is 340 m/s, the distance between the parallel cliff must be

The frequency of light of wave length $$5000\ {\buildrel_{\circ}\over {A}}$$ is:

A progressive sound wave of frequency 500Hz is travelling through air with a speed of $350 ms^{-1}$. A compression maximum appears at a place at a given instant. The minimum time interval after which the rarefraction maximum occurs at the same point , is

If the amplitude of a wave is doubled, what will be the effect on its loudness ?

Each of the properties of sound listed in column A primarily depends on one of the quantities in column B. Choose the matching pairs from two columns.

 Loudness is proportional to
