Power Of A Lens And Combination Of Thin Lenses In Contact
Power of a Lens and Combination of Thin Lenses in Contact:
Power of a lens:
Remember the definition: Power is the measure of a lens’s ability to converge or diverge light.
Use the formula: P = 1/f, where P is power in diopters and f is focal length in meters.
Learn the signs: Positive power (converging lens) and negative power (diverging lens).
Combination of thin lenses in contact:
Effective focal length: Formula - 1/f = 1/f1 + 1/f2 (f1 and f2 are focal lengths of the individual lenses).
Effective power: Formula - P = P1 + P2 (P1 and P2 are powers of the individual lenses).
Diverging lens effect: Reduces effective power by canceling part of the converging power.
