According to Einstein, light travels from one place to another in the form of:
Correct answer: C. Photons
- A. Waves
- B. Particles
- C. Photons
- D. Radiations
Explanation
Einstein proposed that light travels in the form of photons, which are packets of energy that exhibit both wave-like and particle-like properties. This concept is known as wave-particle duality. While light does exhibit wave-like and particle-like behavior, the specific term 'photons' best captures Einstein's theory. The other options, waves, particles, and radiations, do not fully encompass the dual nature of light as proposed by Einstein.

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.
