The diagram shows light passing through an opening and forming bands.

there is an incident beam of light toward an opening in a grating. the light breaks into 7 different paths labeled n = 3, n = 2, n = 1, n = 0, n = 1, n = 2 and n = 3.
which two order bands are the dimmest?

n = 0 and n = 1
n = 0 and n = 3
n = 1 and n = 2
n = 2 and n = 3

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

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 .
