Question

Which equation is Snell’s law for refraction between two media?

विकल्प

• \[n_1\sin r=n_2\sin r\]

• \[n_1\sin r=n_2\sin i\]

• \[n_1\sin i=n_2\sin r\]

• \[n_1\sin i=n_2\sin i\]

Answer 1

Snell’s law relates the refractive indices and angles of incidence and refraction. The product of \[n_1\] and \[\sin i\] equals the product of \[n_2\] and \[\sin r\].
