Blue light has more energy per photon than red light due to its shorter wavelength. This higher energy allows blue light photons to transfer enough energy to electrons in a material to overcome the work function, leading to the photoelectric effect. Red light, with lower energy photons, does not provide enough energy to eject electrons from the material.
What else can I help you with?
Is reverse process of photoelectric effect is zeeman effect?
No, the reverse process of the photoelectric effect is not the Zeeman effect. The Zeeman effect is the splitting of spectral lines in the presence of a magnetic field, while the photoelectric effect is the emission of electrons from a material when exposed to light. They are two distinct phenomena in physics.
Why can't the wave model cannot explain the photoelectric effect?
The wave model cannot explain the photoelectric effect because it assumes that energy is transferred continuously, while the photoelectric effect shows that electrons are emitted instantaneously when light of a certain frequency hits a material. This is better explained by the particle nature of light, as described by the photon theory.
What are the wavelengths for different metals in photoelectric effect?
The wavelengths of light required to cause the photoelectric effect depend on the specific metal. For example, for sodium, the threshold wavelength is around 590 nm, while for potassium it is around 420 nm. Different metals have different work functions, which determine the threshold wavelength needed to eject electrons from their surface.
What are the differences between the Compton effect and the photoelectric effect in terms of their interactions with matter?
The Compton effect involves the scattering of X-rays by electrons, resulting in a change in wavelength and energy of the X-rays. The photoelectric effect, on the other hand, involves the ejection of electrons from a material when it is exposed to light, without any change in wavelength. In terms of interactions with matter, the Compton effect involves interactions with free electrons, while the photoelectric effect involves interactions with bound electrons in atoms.
What did Einstein two papers explain?
Einstein's two papers explained the theory of special relativity and the photoelectric effect. The paper on special relativity introduced the concept of space-time and the relationship between space and time, while the paper on the photoelectric effect explained how light behaves as both a wave and a particle.

What does the slope of the graph of photoelectric current versus intensity signify in the photoelectric effect?
The current rises as does the intensity of light detected. The more light the greater the intensity, and the greater the current. The answer to the question is that photoelectric current displayed on a graph is shown as a slope that varies with the intensity of light. Someimes it can go up, sometimes it can go down.The ultimate answer is that the photoelectric effect is unreliable, but it is improving!
Is Compton effect reverse process of x-rays production?
No,The production of x rays is a reverse process of photoelectric effect. X rays are produced when target metal is bombarded by electrons while in photoelectric effect, the electron are produced when light waves are incident on a metal surface.
Which is the reverse process of x-ray production?
The production of x rays is a reverse process of photoelectric effect. X rays are produced when target metal is bombarded by electrons while in photoelectric effect, the electron are produced when light waves are incident on a metal surface.

Which are the metals which show and do not show photoelectric effect?
All metals will emit a photoelectric effect. However, alkali metals do so in the visible light spectrum, while other metals do so in near-ultraviolet light.The alkali metals are: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr).
What is the difference between particle and wave theory of light?
Particle theory of light, proposed by Isaac Newton, views light as composed of discrete particles called photons. Wave theory of light, formulated by Thomas Young, describes light as a wave propagating through a medium. The wave theory better explains phenomena like interference and diffraction, while the particle theory accounts for aspects such as the photoelectric effect.
Ware did albert Einstein came up with the photoelectric effect?
Albert Einstein developed the theory of the photoelectric effect while working as a patent examiner in Bern, Switzerland in 1905. He proposed that light could be understood as consisting of particles called photons that interact with matter. This theory helped to explain certain behaviors of light that could not be explained by classical physics.
What are the differences between the photoelectric effect and the Compton effect in terms of their interactions with matter and the behavior of photons?
The photoelectric effect involves the ejection of electrons from a material when photons of sufficient energy are absorbed, while the Compton effect involves the scattering of photons by free electrons in a material, resulting in a change in the photon's wavelength. In the photoelectric effect, photons interact with electrons in the material, leading to the ejection of electrons, while in the Compton effect, photons collide with free electrons, causing them to scatter and change direction.
