Ascientist designs an experiment in which a light source is pointed at a substance and a light detector is placed on the opposite side of the substance. when the light source is turned on, the scientist observes that no light is detected on the far side of the substance. what is the best interpretation for this observation? a. the light was either reflected or transmitted by the substance. b. the light was both absorbed and reflected by the substance. c. the light was both reflected and transmitted by the substance. d. the light was either absorbed or reflected by the substance.

When you see distant streetlights through smog, they look dimmer and redder than they do normally. but when you see the same streetlights through fog or falling snow, they look dimmer but not redder. use your knowledge of the interstellar medium to discuss the relative sizes of the particles in smog, fog, and snowstorms compared to the wavelength of light.

Ascientist is working with a new kind of quantum dot to make a dye. he is applying newton’s laws to the particle, but it seems to be breaking these laws of physics. which action will most likely the scientist study the particle’s motion? a. he needs to remember that the particle is too large for quantum analysis. b. he must continue to use newtonian mechanics, but he needs to learn more about the particle. c. he needs to use quantum mechanics, not newtonian mechanics, because this is a nanotechnology product. d. he must determine new physical laws that only apply to quantum dots.
