When subjected to a transverse electric field, cathode rays move

In Thomson mass spectrograph, singly and doubly ionised particles from similar parabola corresponding to magnetic fields of 0.8 T and 1.2 T for a constant electric field. The ratio of masses of ionised particles will be

If the frequency of incident light in Lenard's experiment is doubled, keeping the intensity constant, what will happen to the number of photoelectrons emitted per second?

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, 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)

If $V$ be the accelerating voltage, then the maximum frequency of continuous $X$-rays is given by

Light of frequency $1.8

u_0$(where$

u_0$is the threshold frequency) is incident on a metal surface. If the intensity is quadrupled and the frequency is changed to$0.9

u_0$, what will be the observed photocurrent?

When yellow light is incident on a surface, no electrons are emitted while green light can emit. If red light is incident on the surface, then

Which factor affects the maximum kinetic energy of photoelectrons emitted in Lenard's experiment?

The surface of a metal is illuminated with the light of 400 nm. The kinetic energy of the ejected photoelectrons was found to be 1.68 eV. The work function of the metal is $\left( {hc\; = 1240\;eV - {\rm{nm}}} \right)$
