For a stationary siren on a firehouse is blaring at 81Hz. Assume the speed of sound to be 343m/s, the frequency perceived is mathematically given as'

F=81.721Hz

What is the frequency perceived by a firefighter racing toward the station at 11km/h?

Generally, the equation for the doppler effect is mathematically given as

[tex]F'=\frac{vs+v}{vs}*f[/tex]

Therefore

F=81(343+3.05556)/343

F=81.721Hz

In conclusion, the frequency is

F=81.721Hz
