A source moves towards a stationary observer with a speed of 10m/s. If...
Solution:
Given, speed of sound, v = 330 m/s
Speed of source, vs = 10 m/s
Frequency of source, f = 10 Hz
Let λ be the wavelength of sound heard by the observer.
Using the Doppler's effect formula, we can find the apparent frequency of the sound heard by the observer.
f' = f(v + vs)/(v)
f' = 10(330 + 10)/(330)
f' = 10.303 Hz
The wavelength of sound can be calculated using the formula
λ = v/f'
λ = 330/10.303
λ ≈ 32 m
Therefore, the wavelength of sound heard by the observer is approximately 32m.
Answer: Option A (32m)
Given, speed of sound, v = 330 m/s
Speed of source, vs = 10 m/s
Frequency of source, f = 10 Hz
Let λ be the wavelength of sound heard by the observer.
Using the Doppler's effect formula, we can find the apparent frequency of the sound heard by the observer.
f' = f(v + vs)/(v)
f' = 10(330 + 10)/(330)
f' = 10.303 Hz
The wavelength of sound can be calculated using the formula
λ = v/f'
λ = 330/10.303
λ ≈ 32 m
Therefore, the wavelength of sound heard by the observer is approximately 32m.
Answer: Option A (32m)

A source moves towards a stationary observer with a speed of 10m/s. If...
Apparent frequency F = f(330+v0)/(330+v8)
= 10(330)/(330-10) = 10.31Hz.
Wavelength = 330/F
= 330/10.31
= 32.007m = 32m.
= 10(330)/(330-10) = 10.31Hz.
Wavelength = 330/F
= 330/10.31
= 32.007m = 32m.
