Question

refractive indices of two media are 1.44 and 1.2 respectively if v=4 u=6cm then magnification m=...............​

Answer 1

Step-by-step explanation:

v/u. is the magnification so 4/6

Answer 2

Answer:

The magnification is 0.67.

Explanation:

• The image height to object height ratio is used to determine how much magnification is achieved by a lens, such as that created by spherical mirrors.
• Magnification is represented by the letter m.
• With a convex lens, the magnification for real and inverted images is always negative, whereas it is always positive for virtual and erect images.
• If an object's height is h and an image created by a lens has a height h′, the lens' magnification is given by, the height of the image divided by object height equals m.
• Magnification is also defined as the ratio of the image distance or height to the object distance or height
• M = v/u = 4/6 = 0.67

Thus, the magnification is 0.67.
