Given that the energy difference between the ground state and the first excited electronic state (e) for the sodium atom is 3.373 × 10-19 j, calculate the frequency, , corresponding to a photon possessing this energy. next, calculate the wavelength (in nm) for this photon.

Frequency corresponding to a photon possessing this energy is

Wavelength for this photon is 600 nm.

Explanation:

The relationship between wavelength and energy of the wave follows the equation:

E= energy

= wavelength of the wave

h = Planck's constant  =

c = speed of light =

Thus wavelength for this photon is 600 nm.

The relationship between wavelength and frequency of the wave follows the equation:

where,

= frequency of the wave

c = speed of light  

Thus frequency corresponding to a photon possessing this energy is

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
