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

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
