Photoelectric Effect



E=W+K

@krishkuppuram where is the answer



@pankaj497 can you tell me work function is needed to find in eV .In my solution how to adjust electron in ans 1.5electron

@pratimejaiswal @KrishKuppuram @YashKapoor Please check my mistake and correct it i have been told E(in eV)= 1240/lambda(in nms)

@pankaj497 give full question??


@pankaj497 l have already solve your question .I know that E= 1240/lambda in nm.But there is no use of it in solving this question.Some parameters can be eliminated .If you use it you have to do more calculation and at last you that hc will be eliminated . hc= 1240 in nm.But hc is eleminated while solving question so no need to use it
