Atomic Spectra

Description:

Define a quantum of energy as photon.

Identify a photon as a quantum of energy of electromagnetic radiation.

Realize that shorter wavelength or higher frequency radiation has greater energy

Use the equation E = hf and  E = hc/ λ to calculate the photon energy.

Realizes that energy of a radiation cannot be continuous, but can have only discrete values.

Realize that quantum theory sharply contradicts wave theory which manifests energy as continuous.

Calculate the energy of a photon with wavelength 800nm.

What is the frequency of the radiation emitted if the energy of photon is 10ev?
