Which of the following statements is NOT true? When a light wave encounter a boundary where they must bounce off of a surface with a larger index of refraction, the phase of the wave flips by pi A monochromatic light source is one that consists of many colors The intensity of the center maximum is the largest in a single slit interference pattern The intensity of the center maximum is the largest in a double slit interference pattern

A monochromatic light source is one that consists of many colors

Explanation:

Monochromatic comes from "mono - one, chromatic - color", so a  monochromatic wave has only one wavelength, this means that it has only one color (while it may have different shades or tones). So the correct option is the second one "A monochromatic light source is one that consists of many colors "

The other 3 statements are true.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
