Classical electromagnetism predicted that V0 should have increased as the intensity of the incident light increased. On the contrary, it was found that V0 increased as the frequency f of the light increased. The voltage V0 was found to obey the following linear relationship: V0=mf−b, where m and b are numerical constants (representing the slope and the intercept, respectively). By comparing this equation to your answer from Part B, V0 = (Elight−ϕ)/e, find an expression for the intercept b. (Notice...
Learning Goal: To understand the experiment that led to the discovery of the photoelectric effect.In 1887, Heinrich Hertz investigated the phenomenon of light striking a metal surface, causing the ejection of electrons from the metal. The classical theory of electromagnetism predicted that the energy of the electrons ejected should have been proportional to the intensity of the light. However, Hertz observed that the energy of the electrons was independent of the intensity of the light. Furthermore, for low enough frequencies,...

1) Light of wavelength 310nm is shined on a metal with work function = 1 eV. What will be the maximum kinetic energy of the emitted electrons? 2) Light is shined on a metal with work function 2.0 eV, and electrons are emitted creating a photocurrent. When a decelerating voltage of magnitude 1.0 V is applied, the current goes to zero (i.e. the magnitude of the stopping voltage is 1V). What is the wavelength (in nm) of the incoming light?...
Electrons are emitted from the surface of a metal when it's exposed to light. This is called the photoelectric effect. Each metal has a certain threshold frequency of light, below which nothing happens. Right at this threshold frequency, an electron is emitted. Above this frequency, the electron is emitted and the extra energy is transferred to the electron. The equation for this phenomenon is KE=hν−hν0KE=hν−hν0 where KEKEKE is the kinetic energy of the emitted electron, h=6.63×10−34J⋅sh=6.63×10−34J⋅s is Planck's constant, ννnu...
