What 2 equations are used to calculate energy?
E=hv and E=hc/lambda
What happens to your energy as you increase your frequency?
It increases
Which type of electromagnetic radiation has the longest wavelength?
Radion Waves
A UV light has a wavelength of 4.0E-7 nm what is the energy of one photon of this light?
E=hc/lambda
E= (6.626E-34) (3.0E8)/(4.0E-7nm)
E= 4.97E-19 Joules
