During a certain experiment, light is found to take 33.1 µs to traverse a measured distance of 11.77 km.

1) Determine the speed of light from the data. (Express your answer to three significant figures.)

Part A: What is the speed of light in ethyl alcohol (n=1.36)? 

Express your answer to three significant figures and include the appropriate units. 

Part B: What is the speed of light in lucite (n=1.50)?

Express your answer to three significant figures and include the appropriate units.

The speed of light is now defined to be 2.997 924 58 X 108 m/s. Express the speed of light to (a) three significant figures, (b) five significant figures, and (c) seven significant figures.
