A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness L and index of refraction n =1.5. The wavelength of the laser light in vacuum is L/10 and its frequency is f = 1.5. How long does it take for a short pulse of light to travel from one end of the glass to the other?
