In an experiment to observe the photoelectric effect, electrons are NOT ejected

Question

In an experiment to observe the photoelectric effect, electrons are NOT ejected from a particular metal surface when illuminated by violet light. Which of the following may be capable of ejecting electrons?

a) more than one of answers b, c, d, e is correct

b) LOW intensity EM radiation with a wavelength LARGER than that of visible light

c) HIGH intensity EM radiation with a wavelength LARGER than that of visible light

d) LOW intensity EM radiation with a wavelength SMALLER than that of visible light

e) HIGH intensity EM radiation with a wavelength SMALLER than that of visible light

Explanation / Answer

as for the ability of ejecting electrons

it is not dependent on the intensity of light

but only on the energy of light photon

as energy of light with smaller wavelength is more

the correct option is

a) more than one of answers b, c, d, e is correct

as the correct options are

d) LOW intensity EM radiation with a wavelength SMALLER than that of visible light
e) HIGH intensity EM radiation with a wavelength SMALLER than that of visible light
