Ángulo de incidencia

The video tutorial explains the concept of light reflection, focusing on the angle of incidence and the law of reflection. It describes how a light beam reflects off a surface, forming an angle with a perpendicular line at the point of incidence. The law of reflection is introduced, stating that the angle of incidence is equal to the angle of reflection.

What happens when a beam of light hits a surface?

• It is reflected by the surface.

• It disappears.

• It is absorbed by the surface.

• It passes through the surface.

What is the angle of incidence?

• The angle between the reflected ray and the surface.

• The angle between the incident ray and the perpendicular line to the surface.

• The angle between the incident ray and the surface.

• The angle between the reflected ray and the perpendicular line to the surface.

Which line is used to measure the angle of incidence?

• The surface line.

• The incident ray.

• The perpendicular line to the surface.

• The reflected ray.

According to the law of reflection, how does the angle of incidence compare to the angle of reflection?

• The angles are equal.

• The angle of incidence is smaller.

• The angle of incidence is greater.

• The angles are unrelated.

What does the law of reflection state about the angles involved?

• The angle of incidence is twice the angle of reflection.

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

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

• The angle of incidence is half the angle of reflection.
