Question

what is the energy of radiation with wavelength 500 nm​

Answer 1

Answer:

Wave no. = 1/wavelength

= 1/500 /nm

=0.002 /nm

Explanation:

Answer 2

Answer:

The energy of one photon is (3.9756)($10^{-19}$)

Explanation:

Energy is directly proportional to the number of photons and the electromagnetic frequency and hence frequency is inversely proportional to the wavelength.

As a result, Energy is also inversely proportional to wavelength.

The higher the photon's frequency, the higher its energy OR the longer the photon's wavelength, the lower the energy.

removing the proportionality we obtain a constant in an equation called the plank's constant (h).

where h = 6.626x $10^{-34}$ J Hz-1

∴Energy (E)=hu= $\frac{hc}{lambda}$.

where u is the frequency.

∴E=$\frac{(6.626)(3)(10^{-26} )}{500(10^{-9} )}$=(3.9756)($10^{-19}$)
