The magnification produced by a spherical mirror is -3." List information you can derived from this statement about the mirror/image. Explain your answer also."

• The '-' Minus sign always signifies that the image is inverted.
• In mirrors, the '-' sign always indicates that the image formed is real. This is because the image is formed on the same side of the object
• The magnitude of magnification is greater than 1, it signifies that the image is enlarged. Since magnitude is 3, the image is 3 times bigger than the object.
  
• We can also conclude that the mirror must be a concave mirror. This is because a concave mirror alone can produce a real image of an object.
