Correct answer: B. Electromagnetic
- A. Mechanical waves
- B. Electromagnetic
- C. Matter waves
- D. None of these
Explanation
Electromagnetic waves do not require a medium for their propagation, unlike mechanical and matter waves which do. Therefore, option B is the correct answer. Options A, C, and D are incorrect because they all require a medium for wave propagation.

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.
