A wave travels at a constant speed. How does the wavelength change if the frequency is reduced by a factor of 4?

Respuesta :

Answer:

The product of (wavelength) x (frequency) is always the same number ... the wave's speed.  

So if the wavelength is somehow reduced to  1/4  its original length, the frequency is immediately multiplied by 4 .  That's the only way their product can remain the same.
