An electron is in a certain energy state in a one-dimensional,infinite potential well from x=0 to x=L=200 pm. The electron’s probability density is zero at x=0.300L, and x=0.400L;it is not zero at intermediate values of x. The electron then jumpsto the next lower energy level by emitting light.What is the changein the electron’s energy?

Question

An electron is in a certain energy state in a one-dimensional,
infinite potential well from x=0 to x=L=200 pm. The electron’s probability density is zero at x=0.300L, and x=0.400L;
it is not zero at intermediate values of x. The electron then jumps
to the next lower energy level by emitting light.What is the change
in the electron’s energy?
