Bayar Da Dabbobi Na Nufin

Zamantakewa da Max Planck ta bar a shekarar 1900 inda ya yi aiki a kan black-body radiation. Don haifar da ultraviolet catastrophe, ya faru cewa tattalin arziki yana iya gudanar da su ko kawo waje a discrete packets, ba a continuous. Ya kiran packets “quanta” ko “energy elements”, kuma ya kula energy su da frequency su a simple formula:

E = hf

Idan E ita ce energy of a quantum, f ita ce frequency, da h ita ce constant wanda ake kiran Planck’s constant (6.626 x 10^-34 J s).

Planck’s formula implied that a black body could only emit certain frequencies of radiation depending on its temperature and that higher frequencies require higher amounts of energy. This explains why a black body does not emit infinite amounts of ultraviolet radiation, because it would need infinite amounts of energy to do so.

Planck’s idea was revolutionary because it suggested that energy is quantized, meaning that it can only take discrete values that are multiples of Planck’s constant. This contradicted classical physics, which assumed that energy could take any value.

Planck’s idea was further supported by Albert Einstein in 1905 when he explained another phenomenon that classical physics could not: the photoelectric effect.

The photoelectric effect is the emission of electrons from a metal surface when it is exposed to light. According to classical physics, the number and energy of emitted electrons should depend on the intensity and wavelength of light, respectively.

However, experiments showed that this was not true: instead, the number of emitted electrons depended on the frequency of light, and there was a minimum frequency below which no electrons were emitted at all. The energy of emitted electrons depended on both frequency and intensity: higher frequency meant higher energy, while higher intensity meant more electrons.

Einstein explained this by extending Planck’s idea and assuming that light itself is quantized into packets called photons.

He suggested that each photon has an energy proportional to its frequency, given by the same formula as Planck:

E = hf

He also proposed that when a photon hits a metal surface, it can transfer its energy to an electron. If the photon’s energy is greater than or equal to the work function of the metal, which is the minimum energy required to eject an electron from the surface, then the electron will be emitted with a kinetic energy equal to the difference:

KE = hf – Φ

Where KE is the kinetic energy of the photoelectron, and Φ is the work function of the metal.

Einstein’s explanation of the photoelectric effect showed that light behaves like a particle when it interacts with matter and that its energy is quantized into photons. This was a radical departure from classical physics, which treated light as a continuous wave.

Einstein’s theory of the photoelectric effect was confirmed experimentally by Robert Millikan in 1916, who measured the kinetic energy of photoelectrons as a function of the frequency and intensity of light. He found that the results agreed with Einstein’s predictions and that there was a linear relationship between kinetic energy and frequency, with a slope equal to Planck’s constant.
