A dog can hear sounds in the range from 15
to 50,000 Hz.
What wavelength corresponds to the lower
cut-off point of the sounds at 20^◦C where the
sound speed is 344 m/s?
Answer in units of m.

Solution:

Given that,

A dog can hear sounds in the range from 15  to 50,000 Hz

The speed of sound at a temperature of is: 344 m/s

To find: wavelength

Where,

v is speed of sound

f is the frequency

f = lower cut off point = 15 Hz

Thus the wavelength corresponds to the lower  cut-off point of the sounds is 22.93 meter

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
