How does frequency affect photocurrent?

The presence of a cut-off frequency For any metal surface, there is a minimum frequency of incident radiation below which photocurrent does not occur. The value of this cut-off frequency for the photoelectric effect is a physical property of the metal: Different materials have different values of cut-off frequency.

Does frequency of light affect photocurrent?

In the case of visible light, increase in intensity is seen as increase in brightness. Increase in frequency, is seen as a change in color. Thus, the rate of flow of electrons increases and thus, the photocurrent increases linearly, with intensity of the incident radiation.

What would be the work function of a metal with threshold frequency 10 Hz in terms of Electronvolt?

Ans: The incident frequency is 4.41 x 1014 Hz and the threshold frequency is 5.79 x 1014 Hz, and no photoelectron will be ejected. Example – 13: The photoelectric work function of a metal is 3 eV.

What is the threshold frequency of a metal surface?

the threshold frequency for photoelectric effect for a metal surface is found to be 4.8 x 10^16 hz . the stopping potential required when the metal is iradicated by radiation of frequency 5.6×10^16 hz is.

The work function equals the threshold frequency times Planck’s constant. Planck’s constant is the proportionality constant that relates a photon’s frequency to its energy. Therefore, the constant is required to convert between the two quantities.

What is the frequency of photon whose energy is 66.3 EV?


What is the frequency of a photon whose energy is 6.6 eV?

What is the frequency of a photon whose energy is 66.3 eV? v = 1.6 × 1016 Hz. 2.

What is the frequency of a photon having an energy of?

Substituting h with its value in J⋅s and f with its value in hertz gives the photon energy in joules. Therefore, the photon energy at 1 Hz frequency is 6.62606957 × 10−34 joules or 4.135667516 × 10−15 eV. is used where h is Planck’s constant and the Greek letter ν (nu) is the photon’s frequency.

What is the frequency of a photon with an energy of 66ev?

The correct option is (C) 16 × 10 +15 Hz.
