The thin-lens equation used for lenses is the same equation used earlier for curved mirrors. Is a separate set of equations needed for lenses?
AThere are no new equations to memorize; the mirror equations carry over
BA completely separate set of equations is required for every lens
CLens problems can only be solved using ray tracing, never equations
DOnly converging lenses can use the mirror equations, not diverging ones
Answer & Solution
Correct answer: A. There are no new equations to memorize; the mirror equations carry over
1. There are no new equations to memorise for lenses.
2. The equations already presented for curved mirrors can be used for lenses instead, with careful attention to which quantities apply.
3. Both converging and diverging lenses use the same shared set of equations, just with different signs for f.
