Dual Nature of Radiation question

2009 · Shift 2 · Q40

JEE AdvancedPhysicsDual Nature of RadiationMCQ+3 / −1
Photoelectric effect experiments are performed using three different metal plates p, q and r having work functions ϕp=2.0 eV\phi_p=2.0~\mathrm{eV}ϕp​=2.0 eV, ϕq=2.5 eV\phi_q=2.5~\mathrm{eV}ϕq​=2.5 eV and ϕr=3.0 eV\phi_r=3.0~\mathrm{eV}ϕr​=3.0 eV, respecticely. A light beam containing wavelengths of 550 nm, 450 nm and 350 nm with equal intensities illuminates each of the plates. The correct I-V graph for the experiment is (Take hc = 1240 eV nm)
