Question

state the law of refraction of light explain the term absolute refractive index of the medium and write the expenses to relate if the speed of light in vacuum

Answer 1

first law: The incident rays, point of incident, normal and refracted rays all are lies in the same plane

second law:The ratio of sine angle of incident and sine angle of refraction is a constant

Refractive index:The ratio of speed of light in vaccum and speed of light in a medium is called refractive index

Three lakhs m/s

Answer 2

Hey!!!

Here is ur answer

$1st \: law$
The incident point ,rays , normal and refracted all are lies in same place.

$2nd \: law$

The ratio of sine angle nd incident of refraction is a constant.



$the \: ratio \: of \: speed \: of \: \\ light \: in \: vaccum \: nd \: speed \\ of \: light \: in \: a \: medium \\ is \: called \: refractive \: index.$


Hope it help
