Red laser light of wavelength 650 nm is incident on a double-slit and an interference pattern appears on a screen 2 m away. The distance between the slits is 0.20 mm. What is the path-length difference for the two beams that arrive at the m

answer: electrons

an electric circuit

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 .
