f = C fo / (C + vs)
(Assuming speed of sound, c = 330 m/s),
f = 330 fo / (330 +49 ) frequency that she would hear isf = 0.87 f0

Frequency equals speed divided by what?
Frequency = speed divided by wavelength
What is the formula relating speed of light frequency and wavelength?
the speed of light equals the frequency multiplied by the wavelength.
When working with waves frequency x equals speed?
When working with waves ... or even just talking about them ... (frequency) = (speed) divided by (wavelength) (wavelength) = (speed) divided by (frequency) (frequency) times (wavelength) = (speed)
Frequency multipled by hertz equals speed?
No; hertz is frequency.Frequency times wavelength equals speed of travel.
Why is it not possible to increase the wavelength and frequency at the same time?
Wavelength times frequency equals speed (of the wave). Therefore, unless you also change the speed, if wavelength goes up, frequency goes down, and vice versa.Wavelength times frequency equals speed (of the wave). Therefore, unless you also change the speed, if wavelength goes up, frequency goes down, and vice versa.Wavelength times frequency equals speed (of the wave).

What formula relates speed wavelength and frequency-?
The speed is the product of wavelength and frequency.
When light moves from one medium into another its speed?
Its speed changes but its frequency remains the same.
How does the frequency of a sound wave affect the speed at which the sound wave moves?
Frequency and speed of propagation of the wave are independent of one another. The medium determines the speed of propagation.
What is the speed when wavelength equals 27 meters and frequency equals 97 hertz?
Just multiply the wavelength (in meters) with the frequency (in Hertz) to get the speed (in m/s).
When a wave source moves toward a receiver does the receiver encounter increase in frequency wave speed or both?
Increase in frequency only.
What is the relationship between a wave frequency and its wavelength?
velocity of a wave equals wave frequency times wave length.
Do waves with the shortest wavelengths have the highest frequencies?
That depends on the speed of the waves. If you are considering waves at the same speed, then yes, shorter wavelength equals higher frequency. The formula is: frequency = speed / wavelength or wavelength = speed / frequency From this you can clearly see, that if speed remains constant, then when wavelength decreases the frequency will increase and vice versa.
