Agamma ray with wavelength 1.0 x 1013 meters is passing through empty space. (a) what is the frequency of this gamma ray? ytravel from the sun to jupiter(adistance of 7.8 x 108 km)? 21 suppose that you are viewing a very pure green light. (a) in order to make it appear a very pure red light, one would (select one choice from each set): (increase/decrease) the light wave's (amplitude/frequency/saturation) (b) in order to make it appear a less pure green color (a pastel green for example), one would: (increase/decrease) the light wave's (amplitude/frequency/saturation)

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 .

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
