12.If carbon tetrachloride has an index of refraction of 1.461, what is the speed of light through this liquid? (c = 3 x 108m/s)

A.4.38 x 108m/s

B.2.05 x 108m/s

C.4.461 x 108m/s

D.1.461 x 108m/s​


Sagot :

Answer:

B

Explanation:

Use the equation v=c/n where n = 1.461 and c = speed of light in a vacuum (3x108 m/s).
