V (stopping potential) is plotted against 1/λ, where λ is the wavelength of incident radiations, for two metals
1
Metal 1 may be gold and metal 2 may be cesium
2
θ1 > θ2, if metal -1 is gold and metal -2 is cesium
3
θ1 = θ2 for any two metals
4
θ1 > θ2, if metal -1 and metal -2 are gold and copper respectively
