A metallic surface emits electrons when it is irradiated with a yellow light source of power 25 Watts. What happens to the emission of the electrons if one yellow light source is replaced by two violet light sources of same power?
The number of emission of electrons will increase but the maximum velocity remains the same.
The number of emission of electrons will decrease but the maximum velocity remains the same.
Both the number of emission of electrons and the maximum velocity will decrease.
Both the number of emission of electrons and the maximum velocity will increase.
