Question

According to Snell’s law, ______.

Options

• The ratio of the tangent of the angle of incidence to the tangent of angle of refraction is constant

• The ratio of the cosine of the angle of incidence to the cosine of angle of refraction is constant

• The ratio of the sine of the angle of incidence to the sine of angle of refraction is constant

• The ratio of the angle of incidence to the angle of refraction is constant

Answer 1

According to Snell’s law, the ratio of the sine of the angle of incidence to the sine of angle of refraction is constant.

Explanation:

For a given pair of media and a particular wavelength of light, the ratio of sine of angle of incidence and sine of angle of refraction is constant.
