In a physics lab, light with a wavelength of 530 nm travels in air from a laser to a photocell in a time of 16.7 ns . When a slab of glass with a thickness of 0.870 m is placed in the light beam, with the beam incident along the normal to the parallel faces of the slab, it takes the light a time of 21.3 ns to travel from the laser to the photocell.
What is the wavelength of the light in the glass?
Use 3.00×108 m/s for the speed of light in a vacuum. Express your answer using two significant figures.
Answers: 1
time taken to travel from the source to the photocell via air, 
time taken to reach the photocell via air and glass slab, 
thickness of the glass slab, 
(since light travel with the speed c only in the air)
