Question
Consider the following statements and consider which are true and which are false.The path of a ray of light between two points is the path that minimizes the travel time.
White light that is reflected from a surface will be separated into a visible spectrum.
Light travels faster in glass than it does in a vacuum.
If one stands by a swimming pool, a person standing in the pool will seem to have long legs.
When light enters a medium with a higher index of refraction, the ray is bent closer to the line normal to the boundary.
Explanation / Answer
Light travels fastest in a vacuum (and has been slowed down in Cs atom gas to a few meters/sec) Objects in the water always appear closer than they are...so when super models from Victorias's Secret stand in a pool, they look like they have short legs (which is why they never get photographed standing in pools). Reflection will not cause a seperation of light into a spectrum, but refraction (such as through a diamond or a soap bubble or an oil slick) will. The time is minimized. The light travels in a straight line (we are not considering light paths near large gravitational bodies like black holes). Light bends toward the normal when moving from an optically less dense medium to a more dense (higher index of refraction) one. So, the fellow above me is right, for these reasons.
