If \(\phi\) is the work function of photosensitive material in eV and light of wavelength of numerical value λ=hce metre, is incident on it with energy above its threshold value at an instant then the maximum kinetic energy of the photo-electron ejected by it at that instant (Take h-Planck's constant, c-velocity of light in free space) is (in SI units) : 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
