Question

What is the failure of classical mechanics?

Answer 1

Hint: Classical mechanics is a theory that can be used to examine the motion of low-energy, non-quantum mechanical particles in weak gravitational fields. It's also been extended into the complex realm, where complex classical mechanics behaves similarly to quantum mechanics.


Complete step-by-step solution:
Classical or Newtonian mechanics were unable to explain phenomena such as black body radiation, photoelectric effect, and the temperature dependence of a substance's heat capacity. Classical mechanics could not explain phenomena like the Crompton effect, quantum mechanical tunnelling, and the Raman effect, among others.
1.The wave-like character of particles is ignored by classical mechanics.
2. As a result, it is utterly inapplicable to atoms, where even the tiniest particles, such as electrons, exhibit dual nature (particle and wave-like both)
3. It was due to the failure of classical that quanization was introduced.
4. The concept of black body radiation, which explains how an ideal body can absorb and emit all of the radiation that falls on it. The various frequencies emitted during emission are dependent on the oscillation of electrons in space, however this is not always the case. Classical mechanics was once again demonstrated to be incorrect.
5. The photoelectric effect is a type of photoelectric effect. When light rays of specified frequencies (energy) were incident on the surface of materials, electrons were released, according to observations. It was the intensity, according to Newton, that made the difference. The energy of light was determined by the frequency of incident light, whereas intensity just increased the number of electrons emitted.
The failures of classical mechanics paved the way for quantum mechanics, which provides precise answers to most real-world situations. It not only helps to transcend the limitations of classical, but it also provides solutions to problems on a macro scale.

Note:Despite this, we continue to utilise classical mechanics because, despite failing at the microscopic level, it still reigns supreme at the macroscopic level. In comparison to quantum mechanics, it simplifies calculations in the bigger frame.
