How would you calculate the energy of a photon with a known frequency?

For example, if the frequency is "8x10^13Hz"

Answer 1

Layla Anderson

The energy of the photon can be calculated using #E = hv#

In the formula #E =hv#:

#E# is the energy in Joules #h# is Planck's Constant and #v# is the frequency of the photon (light)

So therefore the Energy of a photon with a frequency of #8*10^13# Hz will be:

#E = hv# #E = 6.626*10^(-34)# #m^2#.#kg#/#s# x #8*10^13# Hz #E = 5.3*10^-20# Joules

Therefore the energy of the photon is #5.3*10^-20# Joules

I hope I was of assistance.

The energy of a photon with a known frequency can be calculated using the equation: E = hf, where E is the energy of the photon, h is Planck's constant (6.62607015 × 10^-34 joule seconds), and f is the frequency of the photon in hertz (Hz).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
