Question

Define Lenz law. And show the formula of refraction of light

Answer 1

Explanation:

Lenz's law states that induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that original flux is maintained through the loop when current flows in it.

And the formula of refraction of light is or refractive index is sin i / sin r or

the velocity of light in air or vacuum / the velocity of light in the given medium.

But in future ask the two questions separately as it might confuse some people.

Answer 2

Answer:

hi

Explanation:

a law stating that the direction

of an induced current is always such as to oppose the change in the circuit or the magnetic field that produces it.

formula=

n=c/v

n ( index of refraction )

c= ( velocity of light in vaccum)

v= ( velocity of light in medium)
