Answer 1

Answer:

Explanation:

Dogs can hear frequencies of up to 45kHz45kHz. What is the wavelength of a sound wave with this frequency traveling in air at 0∘C ​

Answer 2

Explanation:

Solution

Given : Velocity of sound in air v=344 ms

−1

Wavelength of the sound waves λ=

ν

v

For ν

1

=20 Hz, λ

1

=

20

344

=17.2 m

For ν

2

=20 kHz, λ

2

=

20×1000

344

=1.72×10

−2
