What was the reasons for failure of classical mechanics?

What was the reasons for failure 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 does classical physics predict that atoms should collapse?

Classical physics predicts that accelerating charged particles should emit radiation. If this happened, the loss of energy should be accompanied by a spiraling of the electron into the atomic nucleus (akin to the fate of satellites that encounter the atmosphere in low Earth orbit.

Why did classical physics fails to explain the 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.

Did Einstein support quantum mechanics as being fundamental physics or did he think quantum mechanics was incomplete quizlet?

Did Einstein support quantum mechanics as being fundamental physics, or did he think quantum mechanics was incomplete? Einstein thought quantum mechanics is not fundamental but has underpinnings yet to be discovered.

What does Bohr’s correspondence principle say about quantum mechanics versus classical mechanics?

If quantum mechanics were to be applicable to macroscopic objects, there must be some limit in which quantum mechanics reduces to classical mechanics. Bohr’s correspondence principle demands that classical physics and quantum physics give the same answer when the systems become large.

Is there any trouble in the concept of classical mechanics?

There is no trouble in this for the concept of classical mechanics. Just every time, starting to describe a wider class of movements, one must begin with kinematics — derivation of the equation of line, as Newton taught.

Can classical physics explain the shape of the blackbody spectrum?

So far, so good. 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 did Max Planck contribute to the atomic theory?

At about 1900, Max Planck came up with the solution. He proposed that the classical idea that each frequency of vibration should have the same energy must be wrong. Instead, he said that energy is not shared equally by electrons that vibrate with different frequencies. Planck said that energy comes in clumps.

Why has the classic concept of Newtonian mechanics failed?

The classic concept of Newtonian mechanics has not failed. It is based on the derivation of the equation of line and its further solution in the form of first integrals of motion. The equation of line in mechanics is the identical transformation of arc differentials into curvature coefficients.
