Q:

Light travels slowest in

A) Glass B) Water
C) Air D) Vacuum
 
Answer & Explanation Answer: A) Glass

Explanation:

Because the refractive index of glass is highest, light travels slowly in Glass. 

We know that the speed of light depends on the refraction index. The higher the index of refraction is, the slower the speed of light is.


R.I of air and vacuum = 0 (air is a teeny bit more but can be taken as 0)
R.I of water = 1.33
R.I of glass = 1.4.

 

Hence, Light travels slowest in Glass.

Answer & Explanation Answer: C) Saturn

Explanation:

Saturn, the solar system's second largest planet that takes the prize for least dense. It's less dense than water, which has led many people to postulate that it would float.

However, even if it somehow found its way to a body of water large and deep enough to contain it, Saturn would break apart and its rocky core would sink.
