Answers
1- Incident ray, reflected ray and normal will lie in the same plane.
2- Angle of incidence will be equal to the angle of reflection.
Laws of Refraction-
1- Incident ray, reflected ray and normal will lie in the same plane.
2- Refraction depends on the medium through which the light rays travel.
Answer: Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns to the medium from which it originated.
Explanation:
Law of reflection:- As when light rays fall on a smooth surface, the angle of reflection is equal to the angle of incidence, plus the incident ray, the reflected ray, and the normal to the surface are all in the same plane.
The reflected ray is always in the plane defined by the incident ray and is normal to the surface at the point of contact with the incident ray.
Law of reflection of light:- The first law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.
The second law of reflection states that the angle of reflection is equal to the angle of incidence. Both angles are measured with respect to the normal to the mirror.
