  2. Two spherical surfaces bulging outward
  3. Positive focal length
  4. Image is always virtual and diminished

Positive focal length
B
Converging lens
C
Image is always virtual and diminished
D
Two spherical surfaces bulging outward
Solution
Verified by Toppr

The correct option is D Image is always virtual and diminished
A convex lens is a lens which is thin at the edges and thick at the middle. Two spherical surfaces are bulging outward. A convex lens is also known as a converging lens because it bends light towards a single focal point. It has positive focal length. Convex lenses can form two types of images: real and virtual. Convex lenses are the only type of lens that can form real images. Images can be diminished as well as magnified depending upon the position of object.
