You're wrong. The current is limited by the number of electrons per second emitted from the metal surface. Once a steady state current is established the number of electrons per second received by the collecting electrode is the same as the number emitted per second from the metal surface and the speed the electrons travel from the metal to the electrode ...

No because according to particle nature of light there is a collision between an electron and photon. Thus one photon can emit only one electron the rest energy get converted to overcome collisions by other metal atoms and kinetic energy.

You have a misconception, photons are massless, but there is a momentum term that is usually left out of the energy equation. Since a photon has no mass, so it can travel at the speed of light with no problems. You're thinking of e = mc^2, and since a photon has non zero energy, obviously it must have mass? No! That equation is the simple version for the ...

If you are sending some light to a surface there are two ways to send more energy. First, send more photons, each with the same energy. This increases the intensity, but keeps the frequency (and thus the energy per photon) fixed. Second, increase the energy per photon. This requires increasing the frequency. You could do neither (and thus not increase the ...

I want to add to the answer by Floris, which explains the phenomenon correctly. Ask yourself the meanings of stopping potential and the saturation current. The stopping potential is determined by the energy of the photons minus the work function of the material in question. Let's idealize the situation: For example, the work function of copper is 4.7 eV. ...

Essentially this question boils down to "why does the energy of light depend on frequency? The answer is:This is what has been observed, measured, for photons. Light is composed by zillions of photons and the energy of the light wave is dependent on the amplitude of the classical electromagnetic wave. This means many more photons are needed for low ...

The energy $E$ of a photon is directly related to its frequency $f$ via $E = h f$. This relation is a fact of Nature and is described by the Schrodinger equation for the time evolution of a quantum thing $|\Psi\rangle$: $$H |\Psi(t)\rangle = i \hbar \frac{d}{dt}|\Psi(t)\rangle \, .$$ If $|\Psi\rangle$ happens to have a definite energy, then \$H|\Psi(t)\rangle ...
