According to Lambert's law, the intensity of light from a single source on a flat surface at point P is given by Upper L equals k cosine squared (theta )where k is a constant. (a) Write L in terms of the sine function. (b) Why does the maximum value of L occur when thetaequals0?

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

is there a graph

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
