What is the wavelength of a photon of energy of #5.518 * 10^-26# joules?
1 Answer
The length of the wave corresponding to the energy mentioned is about
Explanation:
The link between the energy of a photon and its wavelength can be shown in a formula:
This formula uses wave's frequency, but it can be rearranged so that it uses the length using the formula:
If we combine both formulas we get:
Now we just have to substitute the values:
Now we can reduce the expressions with exponents and calculate just multiplication and division:
Finally we have to calculate the units:
This calculation shows that the formula is correct.
