Explanation:
Given
Speed = 440 m/s
Frequency = 220 Hz
To Find
Wavelength
Solution
We know that
\red{\sf \longrightarrow \lambda=\dfrac{v}{n}}⟶λ=
n
v
Here
\sf \lambdaλ = Wavelength
\sf vv = Speed
\sf nn = Frequency
Units
\sf \lambdaλ = metre (m)
\sf vv = metre per second (m/s)
\sf nn = Hertz (Hz)
According to the question
We are asked to find wavelength
Therefore
We must find "\sf \lambdaλ "
Given that
Speed = 440 m/s
Frequency = 220 Hz
Hence
\sf vv = 440 m/s
\sf nn = 220 Hz
Substituting the values
We get
\orange{\sf \lambda=\dfrac{440}{220} \ m}λ=
220
440
m
Therefore
\pink{\sf \lambda=2 \ m}λ=2 m
Hence
Wavelength = 2 m
