How is Planck's quantum theory related to the photoelectric effect?

E=hf where f is frequency and h is plank's constant.


Who discovered that blue light photons have more energy than red light photons?

Planck in his formula E = hf.This was measured by experimenters long before Planck. Einstein's paper on the photoelectric effect explained the observations, Planck later quantified it. Not sure who did the first experiments that discovered the effect.


What is planck constant?

Planck's constant describes the ratio between the energy of an electromagnetic wave and the frequency of that wave.


Is Planck's constant a non repeating decimal?

No, Planck's Constant is a repeating decimal. 2/3E-33.


What is Planck's constant dimensionally equal to?

Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.


Dimensional formula of planck's constant?

Hi, The original answer was: Planck's Constant = Energy/Frequency = [ML2T-2]/[T-1] = [ML2T-2] So, Dimensional Formula of Planck's Constant = [ML2T-2] In fact, it should read: Planck's Constant = Energy/Frequency = [ML2T-2]/[T-1] = [ML2T-1] So, Dimensional Formula of Planck's Constant = [ML2T-1] Regards, Lho


How does a change in frequency affect Planck's constant?

If Planck's constant could be affected, changed, influenced, impacted, modified, or revised by anything, then it's doubtful that the scientific community would refer to it as a 'constant', regardless of how great Planck was.


Where the Planck's constant equation apply?

E = hv Where h is the Planck's constant v is the frequency of the photon and E is the energy of the photon


What is the meaning of h in the planck's constant?

The meaning of h in the Planck's constant is the photon having a frequency of one unit in any scale.


What is the base unit of Plancks constant?

Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.


Explain how Einstein utilized Planck's quantum concept in explaining the photoelectric effect?

Planck figured out that light was made of particles, and said energy of a quantum = planck's constant*frequency of emitted radiation. Einstein said: 'okay, neither model explains everything-maybe light can be treated as both a wave and a particle (he also came up with the term photon to describe light's particles). He then used Planck's idea to figure out that the energy of a photon depended on its frequency. The logical conclusion was that a given photon must have enough energy to free an electron from the atom-hence, the wave form must have a certain frequency.
