Question

the speed of light in one transparent medium is 2×10^8m/sec find the absolute refractive index of the medium
​

Answer 1

$\huge\mathfrak{Answer}$

$\text{Refractive Index}$

$\dfrac{speed\:of\:light\:in\:vaccum}{speed \:of\:light\:in\:that\:medium} = n = \dfrac{c}{v}$

$\red{Speed\:of\:light\:in\:the\: transparent\:medium}$

$\blue{\boxed{2 \times 10^{8}m/s}}$

$\red{Speed\:of\:light\:in\:vaccum}$

$\blue{\boxed{3 × 10^{8}m/s}}$

$\pink{\boxed{\dfrac{3 \times 10^{8}}{2 \times 10^{8}m/s = 1.5m/s}}}$

$\text{Hence ,the absolute value of}$

$\text{the refractive index is 1.5}$
