The magnification produced by a spherical mirror is -1/3. Analyzing this value, state the type of mirror and the nature and relative size of the image.
Answers
Required solution:
Provided that: The magnification produced by a spherical mirror is -1/3.
To determine:
- Which type of mirror is it!?
- Nature of the image!?
- Size of the image!?
Knowledge required:
• If the magnification produced by a spherical mirror is in negative then the mirror is always “Concave Mirror.”
• If the magnification produced by a spherical mirror is in positive then the mirror is always “Convex Mirror.”
• If magnification is negative in a concave mirror then it's nature is “Real and Inverted” always.
• If magnification is positive in a concave mirror then it's nature is “Virtual and Erect” always.
• If in the ± magnification, magnitude > 1 then the image formed is “Enlarged”.
• If in the ± magnification, magnitude < 1 then the image formed is “Diminished”.
• If in the ± magnification, magnitude = 1 then the image formed is “Same sized”.
Solution:
The mirror is concave mirror. The nature of the image is real and inverted. Size of the image is diminished.
