Get started for freeAt what minimum angle will you get total internal reflection of light traveling in water and reflected from ice?
Will light change direction toward or away from the perpendicular when it goes from air to water? Water to glass? Glass to air?
On the Moonโs surface, lunar astronauts placed a corner reflector, off which a laser beam is periodically reflected. The distance to the Moon is calculated from the round-trip time. What percent correction is needed to account for the delay in time due to the slowing of light in Earthโs atmosphere? Assume the distance to the Moon is precisely, and Earthโs atmosphere (which varies in density with altitude) is equivalent to a layer 30.0 kmthick with a constant index of refraction n=1.000293.
You can often see a reflection when looking at a sheet of glass, particularly if it is darker on the other side. Explain why you can often see a double image in such circumstances.
What is the focal length of a makeup mirror that produces a magnification of \(1.50\)when a personโs face is \(12.0\;cm\) away? Explicitly show how you follow the steps in the Problem-Solving Strategy for Mirrors.
