Concept explainers
The maximum kinetic energy.
To explain: The effect when wavelength is tripled.
Answer to Problem 81GP
Explanation of Solution
Given:
Energy of photons,
Stopping potential,
Formula used:
It is known that:
Where,
Calculation:
Substitute the value in the formula,
If wavelength of photons is doubled, the energy is halved.
If wavelength of photons is tripled, the energy is reduced from
Therefore, no current flows take place.
Conclusion:
When the wavelength of photon is doubled, the stopping potential is
