It is found that yellow light does not eject photoelectrons from a metal. Is it advisable to try with orange light? With green light?

How does the light trevel?

Light from balmer series of hydrogen is able to eject photoelectron from a metal what can be the maximum work function of the metal?

A monochromatic light source of power 5mW emits 8 xx 10^(15) photons per second. This light ejects photo electrons from a metal surface. The stopping potential for this set up is 2V. Calculate the work function of the metal.

Give examples for metals sensitive to UV rays and then for visible light.

If the frequency of light in a photoelectron experiment is doubled the stopping potential will

Light of wavelength 390 nm is directed at a metal electrode. To find the energy of electrons ejected, an opposing potential difference is established between it and another electrode. The current of photoelectrons from one to the other is stopped completely when the potential difference is 1.10 V. Determine (i) the work function of the metal and (ii) the maximum wavelength of light that can electrons from this metal.

What of the following does not happen in the bright light?

A thin prism is made of a material having refractive indices 1.61 and 1.65 for red and violet light. The dispersive power of the material is 0.07. It is found that a beam of yellow light passing through the prism suffers a minimum deviation of 4.0^@ in favourable conditions. Calculate the angle of the prism.
