what happens to the wavelength of a photon after it collides with an electron?
308768
When a photon collides with an electron then the effect of it is called Compton scattering where the photons interact with the electron, losing momentum and therefore increase in wavelength.

Electrons give off photons (light) when they change their energy state and move to a lower electron shell within the atom. Electrons absorb the energy of photons and move up to a higher energy shell within atom. Both are absolutely different from one another.

FREQUENCY OF OSCILLATION x WAVELENGTH = SPEED OF LIGHT We can use this relationship to figure out the wavelength or frequency of any electromagnetic wave if we have the other measurement. Just divide the speed of light by whichever measurement you have and then you've got the other.

In the quantum mechanical view of light, if the photons per area and second are constant, then the intensity is directly proportional to the frequency in concordance with the photoelectric effect. However, in a classical view the intensity of a field depends just on the amplitude, not its' frequency.

Light acts as a wave and can be described by a wavelength λ and a frequency ν. Because the speed of light is a constant, the wavelength and the frequency of light are related to each other: as one increases, the other decreases and vice versa.

The fundamental particle of the electromagnetic force is the photon. Photons have no mass, and they all travel at exactly the same speed; c, the speed of light. The behavior of photons is somewhat mysterious in that they exhibit both particle and wave properties.

As a wave's wavelength increases, the frequency decreases, and as wave's wavelength decreases, the frequency increases. When electromagnetic energy is released as the energy level increases, the wavelength decreases and frequency decreases.

What is the energy of a photon of light having a wavelength of 4.5 x 10-7 meters? (Planck's constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108 m/s) 2.9817 x 10-40 joules. 4.4143 x 10-19 joules.

There's no specific limit for the wavelength of a Photon. Its wavelength can vary from approximately zero to near infinite. It's wavelength will depend on the frequency/ energy of the photon which you are considering.

Frequency (f) and wavelength (λ) are joined by the equation fλ = c, where c is the speed of light. As the speed of light is constant, if you increase the frequency, the wavelength must decrease to maintain this equation and vice versa.

Photon energy. ... The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.

As the electrons in an atom changes its position or as it moves, different colors will appear. The colors that are observed is an indication that definite energy transformations occurs inside the atom emitting light.

The electrons in an atom can only occupy certain allowed energy levels. When an electron drops from a higher energy level to a lower one, the excess energy is emitted as a photon of light, with its wavelength dependent on the change in electron energy.

Which best describes electromagnetic waves moving from gamma rays to radio waves along the electromagnetic spectrum? Wavelength and frequency decrease. Wavelength and frequency increase. ... The wavelength of violet light, rounded to the nearest nanometer, is nm.

Shorter the wavelength, greater is the energy of the photon. It is an inverse relationship. Now shorter the wavelength, greater is the frequency of light also, which correlates directly with the energy of the photon.

Solution: Given, the wavelength of the photon particle = 500 nm. In order to calculate the frequency of the photon particle, we use the formula given above. The frequency of the wave is equal to 6×10-4Hz.

The wavelength λ = h/p is called the de Broglie wavelength, and the relations λ = h/p and f = E/h are called the de Broglie relations. According to De Broglie's equation, wavelength=h/mv. This is the mathematical relation between Kinetic energy and wavelength.
