Question

What is the energy of a photon whose frequency is 5.0x10^14 hz

Answer 1

Answer:

Energy of a photon is $3.313\times 10^{-19}\textrm{ J}$

Explanation:

Given:

Frequency of the photon is, $f=5.0\times 10^{14}\textrm{ Hz}$.

Energy of a photon of frequency $f$ is given as:

$E=hf$, where, $h$ is called Planck's constant.

$h = 6.626\times 10^{-34}\textrm{ J.s}$

So, energy of a photon is:

$E= 6.626\times 10^{-34}\times 5.0\times 10^{14}=3.313\times 10^{-19}\textrm{ J}$

Therefore, the energy of a photon whose frequency is $5.0\times 10^{14}$ Hz is $3.313\times 10^{-19}\textrm{ J}$.
