Hi! so to solve for this, we need to calculate first the wavelength before we could calculate the energy of the photon.
00:08
And how do we do that? we will use rydberg -volmer's equation.
00:13
1 over the wavelength is equivalent to rydberg's constant, rh, multiplied by 1 over the lower energy level, square that, and then minus 1 over the higher energy level, and then square that also.
00:25
So 1 over the wavelength, wavelength is our unknown here, rh is equivalent to 1 .097 times 10 to the power of 7, this is per meter, and then the lower energy level is 1, square that, and then the higher energy level is 5, square that also.
00:42
And then calculating the value on the right side of the equation, we have 10531200 per meter.
00:51
And then we'll take the inverse of both sides of the equation to solve for the wavelength, and this will give us 4 .9 rather, 9 .496 times 10 to the negative 8, and the unit for this is meter...
