Question

As the wavelength decreases, the frequency

increases and energy decreases.
decreases and energy increases.
increases and energy increases.
decreases and energy decreases.

Answer 1

Relationship between wavelength and frequency is : \(\lambda\cdot v = c\) So in solving for the wavelength you have \[\lambda = \frac{c}{v}\] where \(\lambda\) = wavelength and \(c= 3 \ x \ 10^8 \ m/s\) which is the speed of sound.

Answer 2

wavelength and frequency have an inverse relationship, so as one goes up, the other goes down. Can you figure it out?
