How to Calculate the Magnification of a Convex Lens

What is the formula for calculating the magnification of a convex lens?

1. [tex]m = 1 + \frac{d}{f}[/tex]

2. [tex]m = \frac{f}{d}[/tex]

3. [tex]m = 1 - \frac{d}{f}[/tex]

Answer:

The correct formula for calculating the magnification of a convex lens is: [tex]m = 1 + \frac{d}{f}[/tex]

When studying the magnification of a convex lens, it is important to understand the formula that governs this phenomenon. The magnification of a convex lens is determined by the relationship between the distance between the lens and the object, the focal length of the lens, and the resulting magnification factor.

The formula [tex]m = 1 + \frac{d}{f}[/tex] is derived from the principles of optics and is used to calculate how much larger an object will appear when viewed through a convex lens. By knowing the distance [tex]d[/tex] between the lens and the object, as well as the focal length [tex]f[/tex] of the lens, one can plug these values into the formula to determine the magnification factor [tex]m[/tex].

Understanding this formula is essential for anyone working with convex lenses, whether in a scientific setting, photography, or simply when using a magnifying glass. By following this formula, it is possible to calculate the magnification accurately and achieve the desired results when viewing objects through a convex lens.
