Which of the following is true regarding the angle of incidence and refraction in refraction?
The angle of incidence is always greater than the angle of refraction
The angle of refraction is always greater than the angle of incidence
The angles of incidence and refraction are always equal
The relationship between the angles depends on the refractive indices of the two media
According to Snell's law, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for any two given media. This constant depends on refractive indices of the two media. Therefore, the relationship between the angles of incidence and refraction depends on the refractive indices of the two media.
