Define
a)-Angle of Incidence
b)-Angle of Reflection
c)-Angle & deviation
d) Glancing angle.
Answers
Answer:
A)
the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.
B)
the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface.
C)
Angle of Deviation Definition: The angle of deviation is defined as the angle which is obtained from the difference between the angle of incidence and the angle of refraction created by the ray of light travelling from one medium to another that has a different refractive index.
D)
The glancing angle is defined as the angle between the ray of the incident on the plane surface and the surface. An example of a glancing angle is a beam of electrons incident on the crystal.
Explanation:
Please mark me as brainlist.
Answer:
a)The definition of an angle of incidence is an angle made by a light ray or wave hitting a surface and the line perpendicular to that surface.
b) angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface
c)the angle equal to the difference between the angle of incidence and the angle of refraction of a ray of light passing through the surface between one medium and another of different refractive index.
d) angle between a ray incident on a plane surface and the surface, as of a beam of electrons incident on a crystal; the complement of the angle of incidence.
