How does amplitude affect energy of a photon?
When intuition fails: photons to the rescue! The kinetic energy of photoelectrons increases with light frequency. Electric current remains constant as light frequency increases. Electric current increases with light amplitude. The kinetic energy of photoelectrons remains constant as light amplitude increases.
How the energy of a photon is directly proportional to its frequency?
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.
Does energy depend on frequency or amplitude?
The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Who determined that energy is proportional to frequency?
Planck
4. The energy of electromagnetic radiation is directly proportional to its frequency. The phenomenon of it was given by Planck known as Planck’s law, E = hʋ.
Is the momentum of a photon proportional or inversely proportional to its wavelength?
So a photon’s momentum is inversely proportional to its wavelength.
Does amplitude depend on frequency?
Does amplitude depend on frequency? No. Amplitude depends on the total energy of the system, whereas the frequency of an oscillation depends on the properties of the oscillator itself. For a given system, the amplitude can be changed but we cannot change the frequency.
What is the energy of an electromagnetic wave and photon?
Explain how the energy of an electromagnetic wave depends on its amplitude, whereas the energy of a photon is proportional to its frequency Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes this energy is obvious, such as in the warmth of the summer Sun.
What determines the amplitude of an electromagnetic wave?
In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields ( (Figure) ). The wave energy is determined by the wave amplitude. Energy carried by a wave depends on its amplitude.
Can we measure the amplitude of a single photon?
The averages are the things we can actually measure – and these only make sense statistically, when we measure them repeatedly. That’s why the amplitude of a single photon does not make sense. You might want to look into number states and coherent states however, to broaden your view on photons, amplitude etc.
What determines the amplitude of a light field?
In the classical theory, the field is in only a single configuration, and the amplitude one speaks of is linearly related to the amount of energy stored in the field (which is also linearly related to the number of photons os various wavelengths) Highly active question.
