-x3BC-c-speedoflightinvacuum-v-speedoflightinanymedium-v-c-x3BC-x3BC-water-43-x3BC-glass-32Since refractive index is more for glass speed of light will be less in it

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

$μ = \frac{c (s p e e d o f l i g h t i n v a c u u m)}{v (s p e e d o f l i g h t i n a n y m e d i u m)} v = \frac{c}{μ} μ_{w a t e r} {= \frac{4}{3}, μ}_{g l a s s} = \frac{3}{2}$
Since refractive index is more for glass speed of light will be less in it
