Question

An element emits light at a wavelength of 584 nm. What is the energy of the photon with that wavelength?

Answer 1

0.00340239726 ×$10^{-16}$ is the energy of the photon with that wavelength.

What is wavelength?

Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.

The energy of the photon with that wavelength:

E = hv

E = hc/λ

where v = c/λ

h = 6.625 x $10^{-34}$ Js

c = 3 x $10^8$ m/s

λ = 584 nm. x $10^{-9}$ m (1 nm =$10^{-9}$ m)

Putting the values in the equation:

E = (6.625 x $10^{-34}$ Js x 3 x $10^{8}$ m/s) ÷584 x $10^{-9}$ m

E =  1.9875×$10^{-25}$ ÷ 584 x $10^{-9}$

E = 0.00340239726 ×$10^{-16}$

Hence,  0.00340239726 ×$10^{-16}$ is the energy of the photon with that wavelength.
