Question

A beam of light created by a concave mirror occurs when:

Answer 1

The reflection law allows us to find that the correct statement is:

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

Geometric optics studies the geometric properties of light rays by surfaces. It has two laws that describe it:

• The refraction law. This stable how a ray of light is refracted from one surface to another

• The reflection law. Which states that when a ray is reflected off a surface the incident angle is equal to the reflected angle

                     $\theta_i = \theta_r$

Now we can analyze the expressions.

a) False. This only happens if the object is at infinity

b) True. This is the law of reflection that the angles are equal and it always complies

c) False the optical axis is a perpedicular line to the mirror, therefore the ray must be parallel to the mirror and is not reflected.

In conclusion using the reflection law we can find which statement is correct

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