According to Einstein's equation B and C are respectively 1.92 eV the metals which will emit photoelectrons for a radiation of wavelength 4100 Å are The work function for metals A August 21, 2020 Category: Chapter 29 - Dual Nature of Matter and Radiation , NEET Last 32 Years Solved 1988 - 2019 Physics and Chemistry Video Solutions , Physics , Facebook Messenger WhatsApp Share this:TwitterFacebook Related A and B are two metals with threshold frequencies 1.8×10^14Hz and 2.2×10^4Hz. Two identical photons of energy 0.825 eV each are incident on them. Then photoelectrons are emitted by (Take h = 6.6×10^−34J−s)A and B are two metals with threshold frequencies 2.8×10^14Hz and 2.2×10^14Hz. Photons of energy 0.825 eV each are incident on them. Then photoelectrons are emitted in (Take h=6.6×10^−34J−s)The work function for sodium surface is 2.0 eV and that for aluminium surface is 4.2 eV. The two metals are illuminated with appropriate radiations so as to cause photoemission. Then
