Question:

One of the visible lines in the spectrum of hydrogen occurs at 486 nm.

What is the energy of a photon of this wavelength?

Energy

Energy is a property of an object that is required to perform for an object to either heat or work on itself. Energy can neither be created nor destroyed but it can only be converted into other forms.

Answer and Explanation:

Energy is calculated as, E = Plank?s constant * velocity

Speed of light, C is wavelength * velocity and so velocity is C/ wavelength

Therefore, E = {eq}((6.63 * 10 ^{-34} )(3 * 10^8 )} /486 nm {/eq}

Frequency of light is 6.17 * 10

The answer is {eq}4.09 * 10^{14} {/eq}
