The correct Answer is:
To solve the question "A ray of light after reflection from a mirror is known as," we can follow these steps: ### Step 1: Understand the Types of Rays - In optics, there are different types of rays associated with light: - **Incident Ray**: The ray of light that strikes the surface of a mirror. - **Reflected Ray**: The ray of light that bounces off the surface of the mirror after reflection. - **Normal Ray**: An imaginary line that is perpendicular to the surface at the point of incidence. ### Step 2: Identify the Ray After Reflection - The question specifically asks about the ray of light after it has reflected off the mirror. ### Step 3: Choose the Correct Option - Based on the definitions: - The ray that comes towards the mirror is called the incident ray. - The ray that leaves the mirror after bouncing off is called the reflected ray. - Therefore, the correct answer to the question is **Option A: Reflected Ray**. ### Final Answer - A ray of light after reflection from a mirror is known as the **Reflected Ray**. ---
