Thanks for ur excellent key answer. One doubt in que.no. 17. the answer is6×10 to the power of 18. Plz tell me its correct or not
The correct answer is 6X10^18.From the formula C = n(lambda), frequency n = c/lambda,Substituting the known values, 3X10^8 x 24800/12400*10^-10 we get answer.Thanks a lot to Mahesh Sir for his excellent job.
