Reflection

• Are Real Images Always Inverted and Virtual Images Always Erect?
  Real images are inverted and virtual images erect for a real object imaged by one standard lens or mirror, but the rule has limits.
• How Do Mirrors Work?
  Mirrors reflect light because charges in their surfaces respond to incoming electromagnetic waves and emit fields that form a reflected wave.
• What Is the Pole of a Spherical Mirror?
  The pole of a spherical mirror is the point where its principal axis meets the reflecting surface, usually at the center of the mirror’s aperture.
• What Is the Color of a Mirror?
  A mirror is usually described as silver or neutral gray, but its apparent color comes from reflected light and can show a slight green tint.
