Which statement is universally correct?
Correct answer: B. Motion can alter time and space
- A. Motion can alter time but not space
- B. Motion can alter time and space
- C. Motion cannot alter both time and space
- D. None of these
Explanation
The correct answer is (b) Motion can alter time and space.According to the principles of special relativity, motion can affect both time and space. This is known as time dilation and length contraction.Time dilation: Time passes more slowly for an object that is moving relative to an observer. This effect becomes more pronounced as the object's speed approaches the speed of light.Length contraction: The length of an object moving relative to an observer appears to be shorter in the direction of motion. This effect also becomes more pronounced as the object's speed approaches the speed of light.Therefore, motion can alter both time and space, and the statement (b) is universally correct.

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.
