What else can I help you with?
What happens to the energy of photons if the wavelength of light is doubled?
When the wavelength of light is doubled, the energy of photons decreases by half.
What is absolute efficiency in radiation?
Absolute efficiency in radiation measures the probability that a photon will interact with a detector and generate a signal. It is calculated as the ratio of the number of photons detected to the total number of photons emitted. It is an important characteristic used to evaluate the performance of radiation detectors.
What Photons with the highest energy have the blank?
The highest energy photons have the shortest wavelength, which is in the gamma ray range. Gamma rays are a form of electromagnetic radiation that have the highest energy and shortest wavelength in the electromagnetic spectrum.
Photons with the highest energy have?
Photons with the highest energy have shorter wavelengths and higher frequencies. These photons are known as gamma rays and are produced by processes such as nuclear reactions and particle interactions. They are the most energetic form of electromagnetic radiation.
Can you see photons?
No, photons are particles of light that are not visible to the naked eye. They are too small to be seen individually without specialized equipment, such as a photon detector or camera sensitive to light at that level.

What is the longest wavelength photon?
There is no longest wavelength for photons. It can be arbitrarily long.
What are five types of PET imaging coincidence events?
True coincidences: Two annihilation photons are detected simultaneously by the PET scanner. Scatter coincidences: One annihilation photon scatters before being detected, creating a false coincidence event. Random coincidences: Two annihilation photons from different decays are detected simultaneously, leading to a false detection. Detector dead time: Events that occur when the detectors are unable to detect photons due to being in a recovery state. Phantom scattering: Events where photons scatter within the phantom being imaged, leading to erroneous signal detection.
A photon of wavelength 3000 A is absorbed by a gas and remitted as two photons One of the photons is red 7600 A What is the wavelength of the other photon?
The total energy of a photon with a wavelength of 3000 A is divided into two photons, one red photon with a wavelength of 7600 A, and another photon with a shorter wavelength. To calculate the wavelength of the second photon, you can use the conservation of energy principle, where the sum of the energies of the two new photons is equal to the energy of the original photon. This will give you the wavelength of the other photon.
How does the amount of energy in the light changes as the wavelength increases?
The energy of the photons decreases as the wavelength increases
How does a plant frow in artificial lighting?
Same way it grows in sunlight. Photons of light at the right wavelength impact the pigment chlorophyll, excite and electron from the pigment which then enters photosystem II. Photons of the correct wave length are photons of the correct wavelength and the plant does not care what the source is of these photons.
What creates the phenomenon known as the red shift?
The red shift is caused by the Doppler effect, which occurs when light waves from an object moving away from an observer get stretched, causing them to appear more redshifted. This effect is commonly observed in astronomy when measuring the motion of galaxies and other cosmic objects.
What Photons with the highest energy have the blank?
The highest energy photons have the shortest wavelength, which is in the gamma ray range. Gamma rays are a form of electromagnetic radiation that have the highest energy and shortest wavelength in the electromagnetic spectrum.

Why are the photons that emerge from the Sun's surface visible-light photons and infrared-light photons rather than gamma-ray photons?
Photons do not come in different types like infared-photons etc. they are just the wavelength that the photons are at and nuclear fusion just happens to emit photons at a particular wavelength
What do 2 photons of the same frequency have in common?
Wavelength, energy, color (if visible).
