Why Sodium Metal Is Used In Photoelectric Effect? This is because the valence electron are loosely bound to the nucleus of atom and are easily liberated by absorbing small amount of energy. Why sodium is used in photoelectric effect? A sodium photoelectric surface with work function 2.3eV is illuminated and emits electrons. The electrons travel
How Does Frequency Affect Photoelectric Current? We see in photoelectric effect by increasing frequency the K.E of photoelectrons increases. If velocity of electrons increases then time will be less then current should increase then why current remains constant.? Does the photoelectric effect depend on frequency? In the photoelectric effect, light incident on the surface of
How Many Electrons Are Ejected? Each packet or photon could cause one electron to be ejected, which is like having a moving particle collide with and transfer energy to a stationary particle. The number of electrons ejected therefore depends upon the number of photons, i.e. the intensity of the light. How do you find the
Is It Always Possible To See Photoelectric Effect With Red Light? Explanation: Because light behaves like particles rather than a continuous stream, even very high -intensity red light will never be able to overcome an electrons’ work function (in this situation), as every individual photon fails to do so. … Why red light does not
