Questions & Step-by-Step Solutions

A light ray passes through the center of curvature of a concave mirror. What will be the angle of reflection?
  • 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.
  • Reflection of Light – The behavior of light when it strikes a reflective surface, including the law of reflection which states that the angle of incidence equals the angle of reflection.
  • Concave Mirror Properties – Understanding how light rays interact with concave mirrors, particularly the significance of the center of curvature and focal point.
