Answer 1

When the frequency of incident light is halved of its original value i.e. $1.5 v_{0}$ then it becomes less than the threshold value. In that case no photoelectric effect takes place. No photoelectrons would be emitted. The photoelectric current becomes zero.

Answer 2

When the frequency of incident light is halved of its original value i.e. $1.5 v_{0}$ then it becomes less than the threshold value. In that case no photoelectric effect takes place. No photoelectrons would be emitted. The photoelectric current becomes zero.

Light of frequency 1.5 times the threshold frequency is incident on photosensitive material. If the frequency is halved and intensity is doubled, the photo current becomes

zero

When the frequency of incident light is halved of its original value i.e. $1.5 v_{0}$ then it becomes less than the threshold value. In that case no photoelectric effect takes place. No photoelectrons would be emitted. The photoelectric current becomes zero.

In a photoelectric effect experiment if the frequency is above the threshold frequency, then the number of electrons ejected is proportional to:

The number of electrons emitted by a surface exposed to light is directly proportional to, (Provided frequency of incident light is greater than the threshold frequency of metal)

Monochromatic light with a frequency well above the cutoff frequency is incident on the emitter in a photoelectirc effect apparatus. The frequency of the light is then doubled while the intensity is kept constant. How does this effect the photoelectric current?

Intensity of light incident on a photosensitive surface is doubled. Then:
