What is a photon?
a particle of light which essentially is a packet of electromagnetic radiation.
what is the energy of a photon directly proportional to
frequency
What is Planck constant
6.63x10^-34
What is the equation for photon energy
E = Plank constant x speed of light / Wavelength
What is another equation for photon energy?
E=hf
E = plank constant x frequency
What is the energy of a photon inversly proportional to
It’s wavelength
What is a electronvolt
energy transferred to or from an electron when it moves through a potential difference of 1V
what is work done on an electron as it moves through p.d of 1 V
1V x 1.6x10^-19 = 1.6x10^-19
