Answer:
The frequency of the trombonist producing is 245.87 Hz.
Step-by-step explanation:
Given that,
Frequency = 262 Hz
Speed of sound = 337 m/s
Speed = 10.7
We need to calculate the frequency for the trumpet
Using Doppler effect
Where, v = speed of sound
= speed of source
f = frequency
Put the value into the formula


We need to calculate the frequency for the trombonist
Using formula of frequency again
Put the value into the formula



Hence, The frequency of the trombonist producing is 245.87 Hz.
