So it's a more specific version of the equation where we have the n final equal to 2.

当我们令n等于2时,使这个这个方程变成更具体的版本。

Then we would be able to change our equation to make it a little bit more specific and say that delta energy here is equal to energy of n equals 6, minus the energy of the n equals 2 state.

第一激发态，我们就可以把方程,变得更具体一点，能量差,等于n等于6能量，减去n等于2的能量。
