Bohr Model

What implies that photons making up atomic spectra can have only discrete energies?

• The continuous nature of light

• The discrete wavelengths of atomic spectra

• The infinite energy levels within the atom

• The uniform distribution of energy in photons

What is the equation that relates the energy of a photon to its frequency and wavelength?

• E = mc^2

• E = hλ

• E = hv = hc/λ

• E = h/mλ

When are photons produced within an atom?

• When an electron moves to a higher energy level

• When an electron remains in the same energy level

• When an electron moves from one energy level to another within the atom

• When an electron is removed from the atom

How are electronic energies within an atom characterized?

• As continuous and unlimited

• As quantized and limited to specific values

• As variable and dependent on temperature

• As infinite and random
