How are engery and frquency of electromagnetic radiation related?
(The energy of each photon) is (the photon's frequency) times (Planck's Konstant). (The total energy in a beam of it) is (the energy of each photon) times (the number of photons in the beam).
What is photon diffusion time?
photon diffusion time is the ratio of the total radiant energy contained in the volume of the star to the luminosity of the star

What total mass must be converted into energy to produce a gamma photon with an energy of 1.03 10-13 joule?
The mass-energy equivalence principle given by Einstein's formula E=mc^2 can be used to calculate the mass that must be converted. The formula is rearranged to solve for m: m = E/c^2. Plugging in the energy of the gamma photon (1.03 x 10^-13 J) and the speed of light (approximately 3 x 10^8 m/s) will give the required mass.
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.
When electrical energy is converted into thermal energy what must be true?
When electrical energy is converted into thermal energy, the total amount of energy remains constant according to the law of conservation of energy. This means that the energy input from electricity is converted entirely into heat energy and dissipated into the environment, resulting in an increase in temperature of the system or surroundings.
As a candle burns the total amount of energy will what?
As a candle burns, the total amount of chemical potential energy stored in the wax is converted into heat and light energy, so the total amount of energy remains the same.
How many photons are contained in a flash of green light 525nm that contains 189KJ of energy?
To find the number of photons, we need to first calculate the energy of one photon using the formula E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Then, we can divide the total energy (189 kJ) by the energy of one photon to get the total number of photons in the flash of light.
What is the total energy of a projectile if its PE at the apex is 1050j and that value is twice half the maximum kinetic energy of the projectile at landing?
This is a trick question with the 'twice half' words. The energy is 1050 J which is PE at the apex, it is travelling vertically, there is no air resistance, and that energy has been totally converted to KE when the projectile hits the ground.
Why must the total energy output of a hairdryer always equal the total enery input to a hairdryer?
The total energy output of a hairdryer must equal the total energy input due to the law of conservation of energy. According to this law, energy cannot be created or destroyed, only converted from one form to another. In the case of a hairdryer, the electrical energy input is converted into heat and kinetic energy to dry and style hair, meaning the total energy output must match the energy input.
All light has the same amount of energy?
This is a tricky question because there is more than one form of energy in light. There is the energy that each particle of light (the photon) has and there is group energy which is the sum total of all the photon energy as they travel as a group (like in a laser beam). But the good news is that the answer is FALSE for both the photon and group energies. Photon energy depends on the photon fundamental frequency. And the higher the energy the bluer the color, which can run from red to violet. Those photons in the violet color have higher energy than photons in the red color frequency. And group energy is just the sum of all the photon energies in a group, like a light beam from your flashlight (aka, torch). So for a given mix of photons, the more photons in the group the higher is the group energy level. What we call light intensity (e.g., bright or dim) depends on the group energy with high energy equating to high intensity.
What happens when a positron and a electron collide?
When a positron and an electron collide, they annihilate each other and produce gamma rays. This process is known as electron-positron annihilation. The total energy of the particles is converted into electromagnetic energy in the form of gamma rays.
