In a certain camera, a combination of four similar thin convex lenses are arranged axially in contact. Then the power of the combination and the total magnification in comparison to the power (p) and magnification (m) for each lens will be, respectively
Options
- A4 p and 4 m
- Bp^4 and 4 m
- C4 p and m^4
- Dp^4 and m^4
Correct answer
C. 4 p and m^4
Step-by-step solution
When a combination of lens is used then total power aligned P_ net & =P+P+P+P & =4 P aligned Total magnification m _ net = m m m m = m ^4
