A non-inertial frame of reference is that one:
Correct answer: B. Which has some acceleration
- A. Which has zero acceleration
- B. Which has some acceleration
- C. Which is always at rest
- D. None of these
Explanation
A non-inertial frame of reference is a coordinate system or reference frame in which Newton's first law of motion does not hold. In other words, an object in a non-inertial frame experiences an apparent acceleration even in the absence of external forces. This apparent acceleration is often attributed to the effects of motion or acceleration of the frame itself.

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.
