Yes, you’re right. I had (badly) misunderstood the nature of unacademy. It is not linked to NTA. It appears to be a (fairly large... -
NNTesla replied to the thread Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?.I don't understand how did you reach that conclusion. Study material is NOT provided by NTA. As far as I know, only syllabus is provided...

NNTesla replied to the thread Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?.Did your teacher give any reasoning thereof ?

NNTesla replied to the thread Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?.Your reasoning is not correct. In both the cases, A and B, the power of the lens is same. We would be wrong to say that "Both the lens...

NNTesla replied to the thread Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?.The derivation of lens maker's formula already encapsulates the condition of refractive index of medium being different from that of the...
