Waves And Sound Test - 2

The speed of sound does not depend on the frequency of the source.
It just depends on the medium of travel.

The relation is:

V = f. λ

Here, V is speed, f is frequency and λ is wavelength.

As f changes, λ also changes accordingly, making the V same.

Hence, both the frequencies will have the same speed.

The loudness of sound depends on the amplitude.

The shrillness (pitch) of a sound note depends upon frequency. The greater is the frequency, the greater will be the shrillness.

Roaring of a lion produces a sound of low pitch and high intensity/loudness, whereas the buzzing of a mosquito produces a sound of high pitch and low intensity/loudness. This is how the roar of a lion can be differentiated from the buzzing of a mosquito.

The quality of a tone depends upon the overtones that are present there.

He can be recognized because his voice has a definite quality.

Musical instruments do not vibrate at a single frequency: A given note involves vibrations of many different frequencies, often called harmonics, partials, or overtones. The relative pitch and loudness of these overtones give the note a characteristic sound we call the timbre of the instrument.

In an orchestra, the musical sounds of different instruments are distinguished from one another on the basis of quality.
