Notice that the angle involved is the scattering angle not the incident

Photoelectric effect
Photoelectric Absorption. When the photons have energies of 100 keV or less, they are readily absorbed by the electrons in the orbital shells of the atoms of the absorber.
The energy of the photon is transferred to the electron; often dislodging it from its orbit and the remainder of the energy in the photon is used to give the electron kinetic energy or velocity.
These ejected electrons are called photoelectrons and the process is known as photoelectric absorption.
The original photon has given up all of its energy and no longer exists.

This website gives some great info on refraction + some good info on Total Internal Reflection

Awesome activity showing size of everything we know!

Standing waves in a microwave
About 6cm??? therefore λ = 12cm

Use v=fλ
use λ = 12cm
and f = 2450M Hz
to solve for v
