1. What is the Magnification Equation?

The magnification equation (M = -v/u) calculates the magnification of an optical system, where M is the magnification, v is the image distance, and u is the object distance. The negative sign indicates that the image is inverted relative to the object.

2. How Does the Calculator Work?

The calculator uses the magnification equation:

Where:

• \( M \) — Magnification (times)
• \( v \) — Image distance (m)
• \( u \) — Object distance (m)

Explanation: The equation relates the size of the image to the size of the object, with the negative sign indicating image inversion.

3. Importance of Magnification Calculation

Details: Magnification calculation is essential in optics for designing lenses, understanding image formation, and analyzing optical systems in cameras, microscopes, and telescopes.

4. Using the Calculator

Tips: Enter image distance (v) and object distance (u) in meters. Both values must be valid (u cannot be zero).

5. Frequently Asked Questions (FAQ)

Q1: What does negative magnification mean?
A: Negative magnification indicates that the image is inverted relative to the object.

Q2: What is the range of magnification values?
A: Magnification can be less than 1 (reduced image), equal to 1 (same size), or greater than 1 (magnified image).

Q3: When is magnification positive?
A: Magnification is positive for virtual images in mirrors and lenses where the image is upright.

Q4: How does object distance affect magnification?
A: As object distance increases, magnification typically decreases, and vice versa.

Q5: Can magnification be zero?
A: Magnification approaches zero as the image distance approaches zero, but typically won't be exactly zero in practical systems.
