CBSE Class 12-science - Refraction by Lens Videos
Power and combination of a lenses
This video explains problems based on refraction of lenses, Lens maker's formula, Power of lens, Combination of lenses.
- Why don't we use sign convention while deriving lens makers formula?
- obtain the lens formula in case of concave lens
- define lens maker formula
-
sole
- if for a perfectly symmertical lens, r1=r2, then how will we find focal length??
- Is convex always coverging or it depends on the conditions like refractive indices
- a person can see up to 1m the nature n power of which will enable him tosee things at 3m
-
ifany body dare tell this sum answer and post it.
- Derive lens formula for concave lens and state lens formula.
- Derive lens formula for concave lens and state lens formula.
