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, find an expression for the intercept b. (Notice that mf in this equation changes with different light but b is a constant of the metal.) Express your answer in terms of E0 and e.

Respuesta :

The incident light cause the ejection of an electron, the light impart a certain amount of energy to the electron to overcome the forces that constrain it within the metal.  (V0=E light - ∅/e)

How to solve?

The minimum amount of energy required to overcome these forces is called the work function ∅ Different metals will have different values for ∅. For an electron to reach the detector, the light must impart enough energy for the electron to overcome both the work function and the stopping potential.

Part B

Suppose that the light carries energy E light What is the maximum stopping potential V0 that can be applied while still allowing electrons to reach the detector?

Express your answer in terms, е, E light and ∅,

ANSWER: V0=E light - ∅/e

What is the most accurate way to define electromagnetic?

involving or resulting from electricity-produced magnetism, which is the ability of a thing to attract other objects to it. physics. The term "electromagnetic" also refers to the study of the interaction between electricity and magnetism.

What kind of electromagnetic phenomenon is that?

Radio waves, microwaves, infrared rays, visible light, uv light, X-rays, and gamma rays are examples of electromagnetic waves that propagate across space independently of matter.
