Question

define refractive index what is the refractive index of water at 25 degree Celsius​

Answer 1

$\underline{\boxed{\bf{\pink{Refractive\:index:}}}}$

• Refractive index of a medium is defined as the factor by which speed of light reduces as compared to the speed of light in vacuum.
• Refractive index is an unitless quantity.
• Refractive index is a dimensionless quantity.
• More (less) refractive index implies less (more) speed of light in that medium, which therefore is called denser (rarer) medium.

▶ Formula :

$\underline{\boxed{\bf{\purple{\mu=\dfrac{c}{v}=\dfrac{speed\:of\:light\:in\:vacuum}{speed\:of\:light\:in\:medium}}}}}$

✏ Dimensional formula : $\bf{[M^0L^0T^0]}$

⏭ RI of water at 25°C = 4/3 = 1.33
