Chapter 4: Problem 26

According to the laws of reflection, (1) the angle of incidence (i) \(=\) the angle of reflection (r). (2) the incident ray, the reflected ray and the normal lie in the same plane. (3) the incident ray and the reflected ray lie on either side of the normal. (4) All the above

Short Answer

Expert verified

Answer: The second law of reflection states that the incident ray, the reflected ray, and the normal line lie in the same plane. This means that all three entities can be drawn on the same flat surface, confirming that they are all in the same plane.

Step by step solution

Understand the Laws of Reflection

Review the given laws of reflection: (1) the angle of incidence (i) \(=\) the angle of reflection (r). (2) the incident ray, the reflected ray, and the normal lie in the same plane. (3) the incident ray and the reflected ray lie on either side of the normal. (4) All the above laws apply to reflective surfaces.

Create an Example Scenario

Let us consider a flat surface (mirror) with an incident ray, a reflected ray, and a normal line that is perpendicular to the surface at the point of incidence.

Demonstrate Law of Reflection (1)

According to the first law of reflection, the angle of incidence (i) \(=\) the angle of reflection (r). Measure the angle between the incident ray and the normal; this is the angle of incidence. Measure the angle between the reflected ray and the normal; this is the angle of reflection. According to the law, these angles are equal.

Demonstrate Law of Reflection (2)

According to the second law of reflection, the incident ray, the reflected ray, and the normal line lie in the same plane. In the given example scenario, observe that we can draw all three entities (incident ray, reflected ray, and normal) on the same flat surface, which confirms that they lie in the same plane.

Demonstrate Law of Reflection (3)

According to the third law of reflection, the incident ray and the reflected ray lie on either side of the normal line. In the given example scenario, the incident ray approaches the reflective surface from one side of the normal, while the reflected ray leaves the reflective surface from the other side of the normal. All of the above laws have been demonstrated using the example scenario, proving that they govern the reflection of light.
