A converging lens and a diverging lens of equal focal lengths are placed coaxially in contact. The focal length and power of this combination will be |
Focal length ($F_C$) = 0; power of combination ($P_C$) = 0 Focal length ($F_C$) = ∞; power of combination ($P_C$) = 0 Focal length ($F_C$) = 0; power of combination ($P_C$) = ∞ Focal length ($F_C$)= ∞ power of combination ($P_C$) = ∞ |
Focal length ($F_C$) = ∞; power of combination ($P_C$) = 0 |
The correct answer is Option (2) → Focal length ($F_C$) = ∞; power of combination ($P_C$) = 0 |
