Question

Laws of Refraction?...​

Answer 1

$\huge \mathfrak{Answer:-}$

1. Incident ray refracted ray & normal to the boundary are coplanar to the each other.

2. Snell's law:- The ratio of sine of angle of refraction is constant for any given pari of medium.

$\implies$ sin(I)/sin(e) = constant = m2/m1,

$\implies$ m1sin(i) = m2sin(r)

$\implies$ m1 sin(theta1) = me sin(theta2) = me sin(theta3).........

Answer 2

• The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.

• Sin i/ Sin r is equal to constant called refractive index denoted by 'u' this law is called snell's law.

(Laws of reflection are valid for both type of surfaces i.e., for plain as well as spherical refracting faces)
