Answer 1

Laws of Refraction.

Good question,

Here is your perfect answer!

Law 1 : An incident ray, refracted ray and the normal at the point of incidence are in the same plane.

Law 2 : The ratio of sine of incident angle to sine of refracted angle for the same media(mediums) is constant.

sin i/sin r = constant for that medium.

Also known as Snell's law.

Answer 2

$\huge \bf{ \red{ANSWER}}$


$\bf{QUESTION}$
state laws of refraction

1. THE INCIDENT RAY, THE REFRACTED RAY AND THE NORMAL AT THE POINT OF INCIDENCE ALL LIE IN THE SAME PLANE

2. THE RATIO OF SINE OF ANGLE OF INCIDEMCE TO THE ANGLE OF REFRACTION IS CONSTANT


$\bf{ \frac{ \sin(i) }{ \sin(r) } = constant}$

$\bf constant = \mu$
