A electromagnetic wave of light has a wavelength of 500 nm. What is the energy (in Joules) of the photon representing the particle interpretation of this light?

Respuesta :

Answer:

Energy, [tex]E=4.002\times 10^{-19}\ J[/tex]

Explanation:

It is given that,

Wavelength of the photon, [tex]\lambda=500\ nm=5\times 10^{-7}\ m[/tex]

We need to find the photon representing the particle interpretation of this light. it is given by :

[tex]E=\dfrac{hc}{\lambda}[/tex]

[tex]E=\dfrac{6.67\times 10^{-34}\times 3\times 10^8}{5\times 10^{-7}}[/tex]

[tex]E=4.002\times 10^{-19}\ J[/tex]

So, the energy of the photon is [tex]4.002\times 10^{-19}\ J[/tex]. Hence, this is the required solution.
