Classical mechanics or Newtonian mechanics failed to explain the phenomenon like black body radiation, photoelectric effect, the temperature dependence of heat capacity of the substance.
What are the main failures of classical mechanics?
Classical mechanics or Newtonian mechanics failed to explain the phenomenon like black body radiation, photoelectric effect, the temperature dependence of heat capacity of the substance.
Why did classical mechanics fail?
But classical physics could not explain the shape of the blackbody spectrum. The electrons in a hot object can vibrate with a range of frequencies, ranging from very few vibrations per second to a huge number of vibrations per second. In fact, there is no limit to how great the frequency can be.
What are the drawbacks of classical mechanics?
Classical physics fails to explain the motion of heavenly bodies in strong gravitational fields e.g. motion of mercury at its perihelion and also it cannot explain bending of light in vicinity of massive gravitational bodies, gravitational lensing etc.
Which process Cannot be explained by the classical mechanics?
Classical mechanics was unable to explain certain phenomena: black body radiation, the photoelectric effect, the stability of atoms and molecules as well as their spectra. Quantum mechanics, created mainly by Werner Heisenberg and Erwin Schrödinger, explained these effects.
What are the failure of classical physics to explain photoelectric effect?
The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency.
What are the failure of wave theory?
The wave theory of light can perfectly explain some effects of light such as diffraction, polarization, and interference. However, it also fails to prove some theories and observations such as the photoelectric effect and the Compton Effect.

Why does classical physics predict that atoms should collapse?
Why does classical physics predict that atoms should collapse? According to Maxwell's theory, accelerating charged particles should radiate energy in the form of electromagnetic waves. So, according to the classical physics, an electron accelerating around a nucleus should radiate energy continuously.
