it travels faster in water because it is less optically dense then acrylic

Light travels through acrylic at a speed of approximately 200,000 kilometers per second, which is slightly slower than the speed of light in a vacuum.
(speed of lightvacuum) / (refractive indexacrylic glass) = (speed lightacrylic glass):~3.00 x 108 m/s / ~1.491 = ~2.0134 x 108 m/s.
Light will travel at a speed of approximately 200,000 kilometers per second through acrylic, which has an index of refraction of 1.49. This speed is calculated by dividing the speed of light in a vacuum (299,792 kilometers per second) by the refractive index of the material.
Yes, they travel some fast!
Light travels at about 0.66 times the speed of light in a vacuum when passing through ethyl alcohol.
Light travels quickly through a vacuum at a speed of approximately 186,282 miles per second. In other mediums, such as air or water, light travels at a slightly slower speed, but still very fast compared to other things.
