Q
Q: A ray of light passes through the center of curvature of a concave mirror. What will be the angle of reflection?
Solution: When a ray of light passes through the center of curvature, it strikes the mirror perpendicularly, resulting in an angle of reflection of 0 degrees.
Steps: 7
Step 1: Understand what a concave mirror is. A concave mirror is a mirror that curves inward, like the inside of 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 from the mirror's surface.
Step 3: Know what happens when light hits the mirror. When a ray of light hits the mirror, it can reflect off the surface.
Step 4: Determine the angle of incidence. The angle of incidence is the angle between the incoming ray of light and a line that is perpendicular (normal) to the surface of the mirror at the point of contact.
Step 5: Recognize that when the ray passes through the center of curvature, it strikes the mirror perpendicularly. This means the angle of incidence is 0 degrees.
Step 6: Apply the law of reflection. The law of reflection states that the angle of reflection is equal to the angle of incidence.
Step 7: Conclude that since the angle of incidence is 0 degrees, the angle of reflection is also 0 degrees.
