Mirrors and Lenses Quiz

Mirrors

• Types of Mirrors:
  • Plane Mirrors: flat mirrors that produce a virtual image of the same size as the object
  • Spherical Mirrors: curved mirrors that can produce real or virtual images, depending on the object's position
  • Concave Mirrors: curved inward, can produce real or virtual images
  • Convex Mirrors: curved outward, always produce virtual images
• Mirror Equation:
  • 1/f = 1/do + 1/di (where f is the focal length, do is the object distance, and di is the image distance)
• Mirror Formula:
  • Magnification = -di/do (where di is the image distance and do is the object distance)

Lenses

• Types of Lenses:
  • Convex Lenses: thicker in the middle, converge light rays, and produce real images
  • Concave Lenses: thinner in the middle, diverge light rays, and produce virtual images
  • Plano-Convex Lenses: one flat surface and one curved surface
  • Plano-Concave Lenses: one flat surface and one curved surface
• Lensmaker's Equation:
  • 1/f = (n-1)(1/R1 - 1/R2) (where f is the focal length, n is the refractive index, and R1 and R2 are the radii of curvature)
• Lens Formula:
  • 1/f = 1/do + 1/di (where f is the focal length, do is the object distance, and di is the image distance)
• Magnification:
  • Magnification = -di/do (where di is the image distance and do is the object distance)
• Image Formation:
  • Real images are formed on the same side of the lens as the object
  • Virtual images are formed on the opposite side of the lens as the object
