If you increase the frequency what happens to the distance between the waves (wavelength)? The size of the waves stays the same

the distance increases (longer wavelength)

There is no way to tell.

the distance decreases (shorter wavelength)

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
