In a photoelectric cell, the velocity of ejection of an electron emitted depends upon _______?

In a photoelectric cell, the velocity of ejection of an electron emitted depends upon _______?

فوٹو الیکٹرک سیل میں ، خارج ہونے والے الیکٹران کو خارج کرنے کی رفتار _______ پر منحصر ہے؟
Explanation
  • The kinetic energy of ejected electrons depends on the frequency of the incident light, as per Einstein’s photoelectric equation:
    KE=hfϕKE = hf - phi
    where hh is Planck’s constant, ff is frequency, and ϕphi is the work function.
  • Intensity affects the number of emitted electrons but not their velocity.
