Concept explainers
The range of wavelength.
Answer to Problem 18P
Explanation of Solution
Given info:
Energy gap is
Formula used:
Where,
The gap energy equals,
Where,
Calculation:
The energy of photon must be greater than or may be equal to energy gap.
So, longest wavelength that will excite an electron will be:
Conclusion: So, the range of wavelength is
