Question

state the laws of refraction of light with two example for refraction of light in daily life a convex lens of focal length is 10 centimetre calculate its power​

Answer 1

Laws Of Refraction :

1. The incident ray, refracted ray and normal all lie on the same plane.

2. sin i / sin r = constant

f = 10 cm

= 0.1 m

Power = 1 / focal length

= 1 / 0.1

= 10 m

hope it's helpful to uhhh......!!!!!

Answer 2

.it is also known as Snell"s law

it is also known as Snell"s lawlaw of refraction-

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.2.the ratio of sine of angel of incidence to the sine of angle of refraction is a constant.

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.2.the ratio of sine of angel of incidence to the sine of angle of refraction is a constant.f = 10

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.2.the ratio of sine of angel of incidence to the sine of angle of refraction is a constant.f = 10p = ?

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.2.the ratio of sine of angel of incidence to the sine of angle of refraction is a constant.f = 10p = ?p = 100/f(in cm)

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.2.the ratio of sine of angel of incidence to the sine of angle of refraction is a constant.f = 10p = ?p = 100/f(in cm) = 100/10

it is also known as Snell"s lawlaw of refraction-1.the incident ray refracted ray and the normal all lie in same plane.2.the ratio of sine of angel of incidence to the sine of angle of refraction is a constant.f = 10p = ?p = 100/f(in cm) = 100/10 = 10d
