Question

Snell's law of refraction for a given pair of media is expressed as:

Options

• \[n_1 \sin\theta_1 = n_2 \sin\theta_2\]

• \[n_1 \cos\theta_1 = n_2 \cos\theta_2\]

• \[n_1 \sin\theta_2 = n_2 \sin\theta_1\]

• \[\frac{n_1}{n_2} = \sin\theta_1 \cdot \sin\theta_2\]

Answer 1

Snell's law states \[n_1 \sin\theta_1 = n_2 \sin\theta_2\], where \[n_1\] and \[n_2\] are the refractive indices of medium 1 and medium 2, and \[\theta_1\] and \[\theta_2\] are the angles of incidence and refraction measured with respect to the normal.
