Which of the following statement is true?a)A convex lens has – 4...
Explanation:

Convex lens with 4 dioptre power and a focal length of 0.25 m
- The power of a lens is given by the formula: Power (P) = 1 / focal length (f) in meters
- Given that the power of the convex lens is 4 dioptres, we can calculate the focal length using the formula: f = 1 / P
- Substituting the power value into the formula, we get: f = 1 / 4 = 0.25 m
- Therefore, a convex lens with a power of 4 dioptres will have a focal length of 0.25 m.
Therefore, option 'D' is the correct statement as it accurately describes a convex lens with 4 dioptre power and a focal length of 0.25 m.
