Laws of reflection

Choose the correct statement regarding the laws of reflection.

• Angle of incidence < Angle of reflection

• Angle of incidence > Angle of reflection

• Angle of incidence = Angle of reflection

• Angle of incidence + Angle of reflection = 90 degrees.

Identify BD

• Incident ray

• Reflected ray

• Normal

• Emergent ray

According to laws of reflection

• AB = BC

• AB = BD

• <X = <Y

• <X + < Y = 90 degrees

The angle between incident ray and reflected ray is 100 degrees. What is the angle of incidence?

Identify the correct statement regarding laws of reflection.

• Angle of incidence = angle of reflection

  The incident ray, reflected ray, and the normal lie in the opposite plane.

• Angle of incidence < Angle of reflection

  The incident ray, reflected ray and the normal lie in the same plane.

• Angle of incidence = angle of reflection

  The incident ray, reflected ray and the normal lie in the same plane.
