Given with the wavelength of a photon of light, we can use the following equation to solve for the corresponding energy.
00:09
So you have e equals h c over lambda, where e is the energy of the photon expressed in the unit of joules.
00:17
H is the planks constant, c is the speed of light, and lambda is the wavelength that is expressed in the unit of meters.
00:25
So here we're given with a photon that contains energy or that has an energy that is equal to 3 .03 times 10 to the negative 19 joules.
00:44
And we want to find the corresponding wavelength of this button and express it in the unit of nanometers nm.
00:54
So let us rearrange the equation that we have a above to solve for the lambda.
01:02
So, so doing that gives us lambda equals hc over e, over e.
01:09
Where again, h is a planks constant, which value is 6 .626 times 10 to the negative 34.
01:16
C is the speed of light, which is equal to 3 times 10 to the power of 8...
