Materi dualisme partikel dan gelombang, meliputi sifat partikel dari gelombang, sifat gelombang dari partikel, karakteristik gelombang. Transcript of DUALISME GELOMBANG PARTIKEL jika sebuah logam disinari dengan cahaya dan sejumlah fotoelektron dari logam tersebut. Wien dan R-J gagal karena masih menggunakan teori klasik bahwa energi radiasi yang Jika gelombang cahaya dapat berperilaku sebagai partikel.

Fisika Modern – Dualisme Partikel dan Gelombang : : Inspiring the World
Plank made the hypothesis that the oscillator will only take up discrete energies 0, E0, 2E0, 3E0, Geombang dual nature of light l wave theory of light explains most phenomena involving light: The Rutherford model of the atom was an improvement over previous models, but it was incomplete. Quantum Mechanics Photoelectric Effect.
About project SlidePlayer Terms of Service. Published by Cathleen Pope Modified over 2 years ago. Rayleigh – Jean’s Law Maxwell-Boltzman distribution gives the energy state number density N E at energy E as total number of possible energy state and Total energy Hence the average energy: This integration assume continuous distribution of energy, i.
The induced current called photocurrent is collected. Chapter 29 – Particles and Waves.
This was at odds with James Clerk Maxwell’s wave theory of light, which predicted that the energy would be proportional to the intensity of the radiation. Propagation within a uniform medium is along straight lines. The photocurrent is proportional with the intensity.
For a particular electrode and frequency of light, a stopping voltage Vs exists. Auth with social network: The energy of electron is proportional with the frequency. Hitung energi kinetik elektron yang dilepas oleh elektroda tersebut. What are the 3 ways heat can be transferred? To make this website work, we log user data and share it with processors. Who won the Nobel prize for his explanation of the photoelectric effect? A period of time is required to accumulate enough energy for the release of electrons.
Under thermal equilibrium, an object of a finite temperature emit radiation supposed to be EM wave. Share buttons are a little bit lower. This is called UV catastrophe.
Dualisme Cahaya Sebagai Gelombang dan Partikel
Registration Forgot your password? A perfect absorber is an object with black surface that must of the incident energy is absorbed. The frequency reaches the threshold frequency, i.
Planck made an assumption: It is found that an object that absorbs more also emits more radiation. Reflection occurs at the boundary of a medium.
If you wish to download it, please recommend it to your friends in any social system. It is also expected to be a perfect radiator. Consequently, a blackbody is a perfect radiation.
Atas we do the integrationr nthe radiate energy goes to infinity! No photocurrent can be collected regardless of the intensity of light. As n increases r n increases without limit, i. The number of photons striking to the electrode is related to the light intensity IL by Where A is the area of the electrode exposed to light.
In terms of wave theory, the energy is uniformly distributed across its wavefront. There is no measurable tie lag between the illumination of light and the release of photoelectrons.
We think you have liked this presentation. One photon can at most release one electron, regardless of the photon energy Fisika Modern. When the biasing voltage increases from zero, the photocurrent decreases. Experimental Set-up to study Photoelectric Effect 3.
