In a physics lab, light with wavelength 490 nm travels in air from a laser to a photocell
in 17.0 ns. When a slab of glass 0.840 m thick is placed in the light beam, with the
beam incident along the normal to the parallel faces of the slab, it takes the light
21.2 ns to travel from the laser to the photocell. What is the wavelength of the light
in the glass?
A possible means for making an airplane invisible to radar is to coat the plane with an
anti-reflective polymer. If radar waves have a wavelength of 3.30 cm and the index
of refraction of the polymer is n = 1.20, how thick would you make the coating?
State your answer in cm to the nearest 0.001cm.
