Question

An elephant produces 10 Hz sound wave. Assuming the speed of sound in air is 345 m/s. what is the wavelength

Answer 1

Given data : An elephant produces 10 Hz sound wave. Assuming the speed of sound in air is 345 m/s.

To find : What is the wavelength of sound ?

Solution : Speed of sound = 345 m/s and frequency of sound = 20 Hz

Now to find the wavelength of the sound we use formula :

⟹ Speed = Wavelength x Frequency

⟹ ν = λ × f

⟹ 345 = λ × 10

⟹ λ = 345/10

⟹ λ = 34.5 m

Answer : The wavelength of the sound is 34.5 m.

Answer 2

Answer:

Given data : An elephant produces 10 Hz sound wave. Assuming the speed of sound in air is 345 m/s.

To find : What is the wavelength of sound ?

Solution : Speed of sound = 345 m/s and frequency of sound = 20 Hz

Now to find the wavelength of the sound we use formula :

⟹ Speed = Wavelength x Frequency

⟹ ν = λ × f

⟹ 345 = λ × 10

⟹ λ = 345/10

⟹ λ = 34.5 m

Answer : The wavelength of the sound is 34.5 m.
