Photoelectric EffectEasy
Question
Photoelectric emission occurs only when the incident light has more than a certain minimum
Options
A.power
B.wavelength
C.intensity
D.frequency
Solution
According to Einstein’s photoelectric equation
Since Kmax is positive, the photoelectric emission occurs only if
The photoelectric emission occurs only hen the incdent light more than a certain minimum frequency. This minimum frequency is called thershold frequency.
