Law of Reflection

Question 1

characteristic behavior of waves in which the wave bounces back when it hits a surface or any barrier

Answer 1

reflection

Question 2

the line perpendicular to the surface

Answer 2

Normal

Question 3

incoming ray or the ray of light that strikes a surface

Answer 3

Incident ray

Question 4

ray that is thrown back or reflected by the surface

Answer 4

Reflected ray

Question 5

the angle made by the incident ray with respect to the normal

Answer 5

Angle of Incidence (θ_i)

Question 6

the angle made by the reflected ray with respect to the normal

Answer 6

Angle of Reflection (θ_r)

Question 7

the point where the incident ray hits the surface

Answer 7

Point of incidence

Question 8

law of reflection

Answer 8

θ_i = θ_r

Question 9

the angle at which the incident ray strikes the surface of an object is the same as the angle at which it is reflected

Answer 9

law of reflection

Question 10

happens on smooth surfaces wherein light rays reflect off the surface in the same direction. also known as regular reflection

Answer 10

specular reflection
