Newton's Second Law
Net Force = ma
100
Connect the wave frequency to the wave velocity
v = f*lambda
100
How is the energy of a photon affected when you double the frequency?
Energy is doubled.

Ohm's Law
V = IR
200
Connect resistance to power output
P = I^2R or P = V^2/R
200
How is the peak wavelength emitted by an object affected if you double its temperature?
Wavelength is cut in half.
