According to Einstein, bodies and light rays follow a:
Correct answer: C. Geodesics
- A. Rectilinear path
- B. Circular path
- C. Geodesics
- D. Parabolic
Explanation
Geodesics: This is the correct option. According to Einstein's general theory of relativity, bodies and light rays follow paths called geodesics in curved spacetime. Geodesics are the equivalent of straight lines in the curved spacetime geometry predicted by general relativity. Massive objects curve spacetime, and bodies, including light rays, follow the paths dictated by this curvature.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
