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?
