How do you know which photon has the highest energy?
Explanation: The Planck relation states that the energy of a photon is directly proportional to the frequency of the radiation. you see that gamma radiation, with frequencies in the range of 1020Hz is highest.
How does an electric field and magnetic field oscillate with each other?
Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.
What happens to the energy of a photon as the frequency of the wave increases?
From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.
What is produced when electric and magnetic fields vibrate together?
A vibrating electric field, in turn, creates a vibrating magnetic field. The two types of vibrating fields combine to create an electromagnetic wave.
Which photons have the largest energy?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
Which of the following photon is of greater energy?
The photon energy of gamma rays can be considered to be the highest energy since it has the highest frequency in the electromagnetic spectrum.
How are moving electric charges related to electric and magnetic fields?
when the electric charge vibrates the eletric field around it changes causing the magnetic field to change causing the electric field to change and the process continues to create and change the fields. They are perpendicular to eachother and travel outward from the moving charge.
Which physical laws govern the relationship between electric and magnetic field?
Faraday’s Law may be stated roughly as ‘a changing magnetic field creates an electric field’. This is the principle behind the electric generator. Ampere’s Law roughly states that ‘a changing electric field creates a magnetic field’. Thus, this law can be applied to generate a magnetic field and run an electric motor.
What is the relationship between frequency and 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.
What is the relationship between the magnetic and electric fields along the path of a moving electromagnetic wave?
Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate.
What do gamma rays do?
Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells.
Do photons produce electric and magnetic fields?
Photons do not “produce” electric and magnetic fields in the sense that you’re thinking of. Photons (on the one hand) and electromagnetic waves (on the other hand) are alternate descriptions of electromagnetic radiation. The radiation ultimately comes from the same source: oscillating or accelerating charges, in both descriptions. Jan 21, 2009
What happens to a photon during a photoelectric interaction?
• In the photoelectric (PE) interaction, the photon is absorbed by an inner shell (e.g., K shell) electron of an atom. Photoelectric Interaction 17 • All the photon energy is transferred to the electron so that the photon disappears.
What is the charge of a photon?
Light is an electromagnetic wave. i.e. it has both electric and magnetic field. But photon has no electric charge.
Is photon a particle or wave?
The photon however, is a construct of Quantum theory (QM, QED, QCD, QFT). Two different models for light, one considers light as an EM wave, the other as a particle. In the classical picture, an electromagnetic wave is produced by oscillating or accelerating electric charges somewhere.
