Planck's law led to a fundamental change in our thinking about nature of light, what is it? 12. what is "ultraviolet catastrophe"? 13. what the classic physics predicted to be the relation between frequency of black body radiation and its intensity?

where are the vectors ?

so easy. just google the electromagnetic waves and it’ll pop up.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
