Detailed Solution

A bat can hear sound at frequencies up to

130 kHz

. The wavelength of the sound is

2.65 \times 10^{- 3} m

. If the speed of the sound is

344 m / s

.
A bat can hear ultrasonic sound waves, through which it can fly in the night at dark.
The speed of sound is

344 m / s

, and the sound frequency is

130 kHz

v = λϑ

………………………… (1)
Here

v

is the speed of sound,

ϑ =

frequency of sound and

λ =

wavelength
On putting all the values in the equation

(1)

we have,

\Rightarrow 344 = λ \times 130 \times 10^{3}

\Rightarrow λ = 2.65 \times 10^{- 3} m

The wavelength of the sound is

2.65 \times 10^{- 3} m
