Answer:
The wavelength is 0.14 m
Explanation:
Given that,
Frequency = 2450 Hz
Speed of sound = 343 m/s
We need to calculate the wavelength
Using formula of wavelength

Where, v = speed of sound
f = frequency
Put the value into the formula



Hence, The wavelength is 0.14 m
Well the object will have no Momentum since it is not moving, so a small object that is going 10 mph will have Momentum.
