Laws of Reflection

What is the angle of incidence?

• The angle of incidence is the angle formed between the incident ray and the normal to the surface at the point of incidence.

• The angle of incidence is the angle formed between the incident ray and the reflected ray

• The angle of incidence is the angle formed between the reflected ray and the surface

• The angle of incidence is the angle formed between the incident ray and the refracted ray

Define the angle of reflection.

• The angle of reflection is the angle between the incident ray and the surface

• The angle of reflection is always greater than 90 degrees

• The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of incidence.

• The angle of reflection is not affected by the material of the reflecting surface

If the angle of incidence is 30 degrees, what is the angle of reflection?

• 20 degrees

• 30 degrees

• 45 degrees

• 60 degrees

A light ray strikes a mirror and makes and angle 20 degree with the surface. What is the angle of reflection?

• 90 degrees

• 70 degrees

• 60 degrees

• 30 degrees

Explain how the angle of incidence and angle of reflection are related.

• The angle of incidence is greater than the angle of reflection.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is perpendicular to the angle of reflection.

• The angle of incidence is opposite in direction to the angle of reflection.

In a reflection, if the angle of incidence is 60 degrees, what will be the angle between reflected ray and the surface?

• 90 degrees

• 30 degrees

• 60 degrees

• 45 degrees

If a light ray strikes a mirror and makes an angle of 20 degrees with the normal, what will be the angle between normal and reflected ray?

• 40 degrees

• 30 degrees

• 20 degrees

• 15 degrees

Discuss the significance of the numerical laws of reflection in everyday life.

• The numerical laws of reflection play a vital role in designing mirrors, optical devices, and ensuring accurate vision in reflective surfaces.

• The numerical laws of reflection are only applicable in scientific experiments

• The laws of reflection are only relevant in theoretical physics

• Reflection laws have no impact on the functionality of mirrors

In the figure, the incident ray makes 27° with the normal, then find the angle of reflection.

• 27

• 63

• 37

• 90

A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surface. What will be the angle of reflection?
