A convex lens always forms:
Correct answer: C. Both real and virtual images
- A. Real and inverted images only
- B. Virtual and erect images only
- C. Both real and virtual images
- D. Neither real nor virtual images
Explanation
A convex lens can form real images (when the object is beyond the focal point) and virtual images (when the object is between the focal point and the lens).

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
