This was at odds with James Clerk Maxwell’s wave theory of light, which predicted that the energy geolmbang be proportional to the intensity of the radiation. Plank made the hypothesis that the oscillator will only take up discrete energies 0, E0, 2E0, 3E0, Chapter 29 – Particles and Waves.

It is also expected to be a perfect radiator. We think you have liked this presentation. When the biasing voltage increases from zero, the photocurrent decreases. Auth with social network: A period of time is required to accumulate enough energy for the release of electrons.

Consequently, a blackbody is a perfect radiation. A perfect absorber is an object with black surface that must of the incident energy is absorbed. Registration Forgot your password? Quantum Mechanics Photoelectric Effect. This integration assume continuous distribution of energy, i. What are the 3 ways heat can be transferred? No photocurrent can be collected regardless of the intensity of light. Feedback Privacy Policy Feedback.


The dual nature of light l wave theory of light explains most phenomena involving light: The induced current called photocurrent is collected. For a particular electrode and frequency of light, a stopping voltage Vs exists. This is called UV catastrophe.

In terms of wave theory, the energy is uniformly distributed across its wavefront. Hitung energi kinetik elektron yang dilepas oleh elektroda tersebut. About project SlidePlayer Terms of Service.

Dualisme Cahaya Sebagai Gelombang dan Partikel

Propagation within a uniform medium is along straight lines. Atas we do the integrationr nthe radiate energy goes to infinity! The energy loss of a dualismf body is attributable to the emission of electromagnetic waves from the body.

Planck made an assumption: Reflection occurs at the boundary of a medium. Who won the Nobel prize for his explanation of the photoelectric effect? 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. To use this website, you must agree to our Privacy Policyincluding cookie policy.


It is found that an object that absorbs more also emits more radiation. My presentations Profile Feedback Log out. The energy of electron is proportional with the frequency. Share buttons are a little bit lower. The frequency reaches the threshold frequency, i.

Dualisme Cahaya Sebagai Gelombang dan Partikel – ppt video online download

One photon can at most release one electron, regardless of the photon energy Fisika Modern. There is no measurable tie lag between the illumination of light and the release of photoelectrons. As n increases r n increases without limit, i.

Under thermal equilibrium, an object of a finite temperature emit radiation supposed to be EM wave. If you wish to download it, please recommend it to your friends in any social system. Experimental Set-up to study Photoelectric Effect 3. The photocurrent is proportional with the intensity.
