Q: A light ray passes through the center of curvature of a concave mirror. What will be the angle of reflection?
Solution: When a light ray passes through the center of curvature, it strikes the mirror perpendicularly, resulting in an angle of reflection of 0 degrees.
Steps: 6
Step 1: Understand what a concave mirror is. A concave mirror is a mirror that curves inward, like a bowl.
Step 2: Identify the center of curvature. The center of curvature is a point located at a distance equal to the radius of the mirror's surface.
Step 3: Know that when a light ray hits a mirror, it can reflect off the surface. The angle at which it reflects is called the angle of reflection.
Step 4: When a light ray passes through the center of curvature, it hits the mirror straight on (perpendicularly).
Step 5: When light hits a surface perpendicularly, it reflects back along the same path.
Step 6: Since the light ray reflects back along the same path, the angle of reflection is 0 degrees.
