Step 1: Identify the angle of incidence.
The angle of incidence is the angle between the incident ray and the normal (the dashed line perpendicular to the mirror).
From the diagram, the angle of incidence is 40∘.
Step 2: Identify the angle of reflection.
The angle of reflection is the angle between the reflected ray and the normal.
From the diagram, the angle of reflection is 40∘.
Step 3: State the Law of Reflection.
The diagram illustrates the Law of Reflection, which states that the angle of incidence is equal to the angle of reflection.
Step 4: Verify the law with the given angles.
In this case, the angle of incidence (40∘) is equal to the angle of reflection (40∘).
The angle of incidence is 40∘.
The angle of reflection is 40∘.
