NEET Physics Refraction MCQ Question
A diagram illustrates a double convex lens where an object O is placed and forms an image I1 at the first refracting surface ABC, which then acts as a virtual object for the second surface ADC, finally forming an image at I. Which equation represents the refraction at the interface ABC for this system?
n1/OB + n2/BIC = n2 - n1/BC
n1/OB + n1/BIC = n2 - n2/BC
n2/OB + n1/BIC = n1 - n2/BC
n2/OB + n2/BIC = n1 - n1/BC
Correct Answer
Detailed Explanation
The correct equation for refraction at the interface ABC is n1/OB + n2/BIC = n2 - n1/BC, as derived for the first refracting surface in the NCERT context.
