Define a reflection of light.
b. incident ray
c. point of incidence
d. normal
e. reflected ray.
Answers
Answer:
1)Incident ray - A ray of light falling on the surface separating two mediums is the incident ray. Refracted ray - A ray of light traveling in another medium, with change in direction is the refracted ray. Angle of incidence - The angle which the incident ray makes with the normal is called angle of incidence.
2)In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic
3)When a line is drawn perpendicular to the reflecting surface at the point of incidence, this line is known as normal. It is the imaginary line which is perpendicular to the reflecting surface. The normal ray is incident at 90 degrees to the reflecting surface.
4)The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface. The angle between the surface normal and the reflected ray is known as the angle of reflection

Answer:
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves
b... An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface.
c....In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray and so on
d...Normal at point of incidence: A line drawn perpendicular on the surface (i.e. making 90° angle with the surface) of an object at the point of incidence is called a normal point of incidence. Angle of incidence: The angle formed between the incident ray and the normal is called the angle of incidence.
e....Reflected ray. A ray of light or other form of radiant energy which is thrown back from a nonpermeable or nonabsorbing surface; the ray which strikes the surface before reflection is the incident ray.
