this h nu, here h nu corresponding this wavelength ok, corresponding this frequency, so that is now that is even less than the this that is e V, not e V what I should tell this h nu whatever this energy of this photons, that energy is less than the work function.
अर्थात ये ऊर्जा या इसके संगत ऊर्जा eV से भी कम है , ओह , मुझे कहना चाहिए इस फोटोन की ऊर्जा वर्क फंक्शन से कम है ।
