Question

complete the table by static measurement of angle of incidence and angle of reflection for angle of incidence 15 degree 80 degree 90 degree angle of reflection 50 degree 25 degree​

Answer 1

Answer:

Explanation:

Angle of incidence is always equal to the angle of reflection.

Therefore in the table,

a) 15 degrees

b) 50 degrees

c) 25 degrees

d) 80 degrees

e) 90 degrees( incident and reflected rays coincide in this case )

Answer 2

Answer:

In the diagram, the ray of light approaching the mirror is known as the incident ray (labeled I in the diagram). The ray of light that leaves the mirror is known as the reflected ray (labeled R in the diagram). At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is known as a normal line (labeled N in the diagram). The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection. (These two angles are labeled with the Greek letter "theta" accompanied by a subscript; read as "theta-i" for angle of incidence and "theta-r" for angle of reflection.) The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
