Question

State whether given statement is True or False
Light travels at a lower speed in water than in glass.

• A. True
• B. False

Answer 1

The correct option is B False

$\mu =\frac{c\left(speedoflightinvacuum\right)}{v\left(speedoflightinanymedium\right)}v=\frac{c}{\mu }{\mu }_{water}{=\frac{4}{3},\mu }_{glass}=\frac{3}{2}$

Since refractive index is more for glass speed of light will be less in it
