What is planks constant?
Scientists who fired electrons at a nickel target which scattered and produced an interference pattern, hence validating De Broglie's matter-wave hypothesis.
Who are Davisson & Germer?
Mr's "Music is more important than physics so we get to leave class early"

If the magnitude of centripetal force on an object remains the same but the radius of its path is increased, what will be the resulting effect on its period?
What is an increase in period?
The path a charge takes relative to an electric field and the path is takes relative to a magnetic field.
E field path is parabolic due to constant acceleration in one direction, B field path is circular (or spiralled if v at an angle to B) due to constant centripetal acceleration.
Two equations on your formula sheet that provide evidence for the wave model of light.
What are Young's interference eqn and Malus' Law?
