Pretend that a person can walk only at a certain pace—no faster, no slower. If you time her uninterrupted walk across a room of known length, you can calculate her walking speed. If. however, she stops momentarily along the way to greet others in the room, the extra time spent in her brief interactions gives an average speed across the room that is less than her walking speed. How is this similar to light passing through glass? In what way does it differ?

How far does light travel underwater during a time interval of 1.50106 s?
Consider the following materials with the following values for permeability and permittivity. In which material will light travel with the fastest speed?
Light has been argued to be a wave and then a particle, and then back again. Does this indicate that light’s true nature probably lies somewhere between these two models?
Galileo proposed measuring the speed of light by uncovering a lantern and having an assistant a known distance away uncover his lantern when he saw the light from Galileo’s lantern, and timing the delay. How far away must the assistant be for the delay to equal the human reaction time of about 0.25 s?
Does the fact that the light flash from lightning reaches you before its sound prove that the speed of light is extremely large or simply that it is greater than the speed of sound? Discuss how you could use this effect to get anestimate of the speed of light.

Sunlight and star light passing into and through the earth’s atmosphere is alwaysbent towards the vertical (normal). Does this mean the star is not where it appearsto be?
