In a photoelectric experiment, the incident light frequency is $3

u_0$, where$

u_0$is the threshold frequency. If the frequency is reduced to$1.5

u_0$ and the intensity is kept constant, how does the stopping potential change?

When monochromatic radiation of intensity $I$ falls on a metal surface, the number of photoelectron and their maximum kinetic energy are $N$ and $T$ respectively. If the intensity of radiation is $2I,$ the number of emitted electrons and their maximum kinetic energy are respectively

A source emits monochromatic light of wavelength 600 nm with a power of $3.3 imes 10^{-3}$ W. Calculate the average number of photons emitted per second. (Given: $h = 6.6 imes 10^{-34}$ Js)

The photoelectric effect represents that

The magnitude of saturation photoelectric current depends upon

The variation of photoelectric current given by the photocell, with the intensity of light, is give by a graph, which is a straight line with

When wavelength of incident photon is decreased then

If the energy of photons corresponding to the wavelength of 6000$\mathop A\limits^ \circ$ is $3.2 imes {10^{ - 19}}$ J, the photon energy for a wavelength of 4000$\mathop A\limits^ \circ$ will be

In Lenard's experiment, if the intensity of the incident light is doubled while keeping the frequency constant, what will be the effect on the stopping potential?

The time taken by a photoelectron to come out after the photon strikes is approximately

In Lenard's experiment, a metal with a work function of 2.0 eV is illuminated by light of frequency $6 imes 10^{14}$ Hz. What is the kinetic energy of the emitted photoelectrons? (h = $6.63 imes 10^{-34}$ Js)
