Define absolute refractive index of a medium. Find its value for glass in which speed of light is `2 xx 10^(8)m//s`. |
|
Answer» Absolute refraactive index of a medium, `n = ("velocity of light vacuum" (c ))/("velocity of light in the medium" (v))` For glass, `n=(3 xx 10^(8) m//s)/(2 xx 10^(8) m//s) =1.5`. |
