In super position of waves, when we calculate intensity then we say intensity is directly propotion to square of amplitude and remove proportionality sign by a constant k.
I would like to know the value of k wether it has some numeric value or it is property of light or something.
Sir, when the rays converge, converging wave front is formed as you told in case of convex lens, but the rays even continue after that so can we say that progressively diverging rays are also produced?
What is dimension
I think answer (a) is correct
