Question

71.What colour light will produce photoelectrons with highest average
kinetic energy​

Answer 1

Answer:

the answer is zero I hope it is helpful for you

Answer 2

According to Heisenberg's uncertainty principle, it is impossible to precisely measure or calculate an object's position and momentum.

The explanation is as follows:

• It is impossible to measure both position x and momentum p at the same time, according to Heisenberg's Uncertainty Principle.
• Use xp⩾ h/4π
• As x -> 0 then p -> ∞
• Neither uncertainty can be zero in this case, and if the position is zero, the momentum uncertainty becomes infinite.

What color light will produce photoelectrons with the highest average kinetic energy?

• Because blue light has higher kinetic energy, it produces photoelectrons with the highest kinetic energy.
• The maximum kinetic energy of photoelectrons is thus determined by the frequency of incident light and the material of the emitter plate.
