- The incident ray, the refracted ray, and the normal all lie in the same plane at the point of incidence.
- The angle of incidence is always equal to the angle of refraction when light passes from one medium to another.
Answer: Only 1
Notes: Statement 1 is correct as it aligns with the law of refraction. Statement 2 is incorrect; according to Snell's law, the ratio of the sines of the angles, not their values, remains constant for given media. Thus, the angle of incidence generally does not equal the angle of refraction.
