Physics

In a photoelectric effect experiment a light of frequency $1.5$ times the threshold frequency is made to fall on the surface of photosensitive material. Now if the frequency is halved and intensity is doubled, the number of photo electrons emitted will be:

If the energy of a photon corresponding to a wavelength of $6000 \mathring A$ is $3.32 \times {10^{ – 19}}J$, the photon energy for a wavelength of $4000 \mathring A$ will be ………… $eV$

medium

One milliwatt of light of wavelength $4560\ \mathring A $ is incident on a cesium surface of work function $1.9\ eV$. Given that quantum efficiency of photoelectric emission is $0.5\%$. Planck's constant $h = 6.62 \times 10^{-34}\ J-s$, velocity of light $= 3 \times 10^8\ ms^{-1}$, the corresponding photo electric current is
