Question

estions
1. What are wavelength. frequency
time period and amplitude of
sound wave?
2. How are the wavelength and
frequency of a sound wave
related to its speed?
3. Calculate the wavelength of a
sound wave whose frequency is
220 Hz and speed is 440 m/s in
a given medium
1. A person is listening to a tone of
500 Hz sitting at a distance of
450 m from the source of the
sound. What is the time interval
between successive compressions
from the source?
mount of sound energy passing each
through unit area is called the
ha​

Answer 1

$\huge \bold \red {❥answer}$

1. The distance between two consecutive compressions or two consecutive rarefactions is known as the wavelength.
2. The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The more rigid (or less compressible) the medium, the faster the speed of sound.
