Ángulo de reflexión

The video tutorial explains the concept of reflection, focusing on how a light beam or ray reflects off a surface. It introduces the angle of reflection, which is formed by the reflected ray and a line perpendicular to the surface. The tutorial also covers the law of reflection, stating that the angle of reflection is equal to the angle of incidence.

What happens when a light beam hits a surface?

• It disappears.

• It is reflected by the surface.

• It passes through the surface.

• It is absorbed by the surface.

What is the angle of reflection?

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

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

• The angle between the reflected ray and the surface.

• The angle between the incident ray and the surface.

Which line is used to measure the angle of reflection?

• A line at 45 degrees to the surface.

• A line perpendicular to the surface.

• A line at 90 degrees to the incident ray.

• A line parallel to the surface.

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

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

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

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

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

What does the law of reflection state?

• The angle of incidence is always zero.

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

• The angle of reflection is always zero.

• The angle of reflection equals the angle of incidence.
