Question

3 sin a=6 sin b=2√3 sinc then angle a=​

Answer 1

Answer:

Snell's law of refraction states that the product of sine of angle made by the ray in a medium and the refractive index of that medium is constant i.e. n

1

×sini= constant

We get n

1

sini=n

2

sinr

⟹

n

2

n

1

=

sini

sinr
