Question

The velocity of light in two media'x' and'Y are 10^(8)ms^(-1) and 1.5times10^(8)ms^(-1) respectively.The refractive index of y with respect to X is Options (a) (2)/(3) (b) 2 (c) (1)/(2) (d) (2)/(3)​

Answer 1

Answer:

Speed in medium X =

$10 \times {10}^{8} m {s}^{ - 1}$

Speed in medium Y =

$1.5 \times {10}^{8} m {s}^{ - 1}$

Refractive Index Y w.r.t. X =

Speed in medium X / Speed in medium Y

=

$(10 \times {10 }^{8} ) \div (1.5 \times {10}^{8} )$

=
