What distance does light travel in water, glass, and diamond during the time that it travels 1.0 m in vacuum? the refractive indices for water, glass, and diamond are 1.33, 1.50, and 2.42, respectively.

distance travelled in water = 1 / 1.33 = 0.75 m

distance travelled in glass = 1/ 1.5 = 0.66 m

distance travelled in diamond = 1/ 2.42 = 0.41 m

Explanation:

velocity of light in water, glass and diamond will be 1/1.33 , 1/1.5 and 1/2.42 times respectively of that in vacuum. So distance travelled in these mediums will be less.

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .
