Question

Explain effect of frequency ?

Answer 1

When f = 0, XC is infinite ( ) and decreases as frequency increases. That is, the lower the frequency, the greater the capacitive reactance; the higher the frequency, the less the reactance for a given capacitor. As shown in figure 1-3, the effect of capacitance is opposite to that of inductance..

Answer 2

Effect of frequency on PhotoelectricEffect. ... An increase in frequency of the incident light increases the kinetic energy of the emitted electrons, so greater retarding potential is required to stop them completely.
