SPHERICAL MIRRORS

• Spherical Mirrors are mirrors cut out from a spherical reflecting surface.
• 2 types of spherical mirrors:

  • Concave Mirror
  • Convex Mirror
• What does the term C symbolize in spherical mirrors?

  Center of the Curvature
• What does the term V symbolize in spherical mirrors?

  Vertex
• What does the term R symbolize in spherical mirrors?

  Radius of the Curvature
• What does the term AB symbolize in spherical mirrors?

  Aperture
• What does the term F symbolize in spherical mirrors?

  Principal Focus
• What does the term f symbolize in spherical mirrors?

  Focal length
• Center of Curvature - Center of the sphere
• Vertex - Center of the mirror.
• Vertex - Sometimes is called the pole of the mirror.
• Vertex - Sometimes is called the pole of the mirror.
• Radius of the Curvature - Radius of the sphere
• Radius of Curvature - Distance between C and V
• Principal Axis - also called as Optical Axis
• Principal Axis - also called as Optical Axis
• Principal Axis - Width of the mirror
• Principal Focus - Point where the reflected rays meet as in the case of a converging mirror, or the point where the reflected rays seem to come from behind a diverging mirror.
• Focal Length - Distance from the vertext to the principal focus.
• Formula to get the Focal length:

  f = 1/2R
• Concave Mirror - Also known as Converging Mirror
• Concave Mirror - Also known as Converging Mirror
• Convex Mirror - Also known as Diverging Mirror
• Convex Mirror - Also known as Diverging Mirror
• Concave Mirror - Your image will become smaller and upside down. You will become larger as you get closer, beyond a certain point, your image will become upright.
• Convex Mirror - Your iamge will become smaller and upright.
• Rule 1 states that if a ray of light is parallel to the principal of axis, it will always pass through the focus.
• Rule 1 states that if a ray of light is parallel to the principal of axis, it will always pass through the focus.
• Rule 1 states that if a ray of light is parallel to the principal of axis, it will always pass through the focus.
• Rule 2 states that if a ray passes through the center of curvature, it will reflect to the same path.
• Rule 2 states that if a ray passes through the center of curvature, it will reflect to the same path.
• Rule 2 states that if a ray passes through the center of curvature, it will reflect to the same path.
• Rule 3 states that if a ray of light passes through the focus, it will become parallel to the principal axis.
• Rule 3 states that if a ray of light passes through the focus, it will become parallel to the principal axis.
• Rule 3 states that if a ray of light passes through the focus, it will become parallel to the principal axis.
• Rule 4 states that if a ray of light was incident at the pole of a concave mirror, it is reflected back, making the same angle with the principal axis.
• Rule 4 states that if a ray of light was incident at the pole of a concave mirror, it is reflected back, making the same angle with the principal axis.
• Rule 4 states that if a ray of light was incident at the pole of a concave mirror, it is reflected back, making the same angle with the principal axis.
