Calculating the Object Distance for Magnification -1 in a Concave Mirror
Given data:
- Focal length (f) = 10 cm
- Magnification (m) = -1
Determination of the Object Distance:
- The magnification formula for a concave mirror is given as: m = -v/u
- Where, v is the image distance and u is the object distance
- Since the magnification is given as -1, we have m = -1 = -v/u
- Therefore, v = -u
Using the Mirror Formula:
- The mirror formula for a concave mirror is: 1/f = 1/v + 1/u
- Substituting v = -u in the formula, we get: 1/f = 1/(-u) + 1/u
- Simplifying the equation, we get: 1/f = 0
- This implies that the object distance should be at infinity in order to produce an image of magnification -1
Conclusion:
- In conclusion, for a concave mirror with a focal length of 10 cm, an object should be placed at infinity to produce an image of magnification -1.
