breadth =8cm

Perimeter of rectangle

=2(l+b)

=2(15+8)

=2(23)=46cm

Answer 2

Answer:

following are the laws of refraction:

1)it state that the incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence all lie in the same plane .

2)the ratio of sine of angle of incidence to the sine of angle of refraction is a constant.

sin i/sin r=constant
