Magnification m = -v/u = -(-10)/20 = 0.5.

Using the lens formula and magnification formula, we find the magnification m = -v/u = -1.

Magnification (m) = -v/u. Here, v = -5 cm and u = -10 cm, so m = -(-5)/(-10) = 2.

Magnification (m) = -v/u = -(-5)/(-15) = 1/3. Therefore, the magnification is 3.

When the object is placed at the focus of a concave mirror, the image is formed at infinity, leading to infinite magnification.

Magnification (m) = v/u. For an object at 2f, the image distance v = 2f, so m = 2f/(2f) = 1.

Magnification (m) = image distance/object distance = 45/15 = 3.
