reflection
the bending and scattering of a wave as it
hits an object or opening
diffraction
the bending of a wave as it passes through
media
refraction
the bouncing of a wave after it hits an object
absorption
the taking in of a wave by an object as the
wave hits it
transmission
the passing of a wave through an object

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?
