Question: Set up appropriate equations and solve the given stated problems. All numbers are accurate to at least two significant digits.
A beam of light travels 4.50 m from the source to a water tank and then through the tank in 1.67 x 10-8 s. If the speed of light in air is 3.00 x 108s, and in water is 2.25 x 108 m/s, how far does the beam travel through the water tank (neglect the glass walls)? see Fig.
