No, photon energy is not the same for all wavelengths of light. The energy of a photon is directly proportional to its frequency, so different wavelengths of light can have different photon energies. Shorter wavelengths of light have higher energy photons, while longer wavelengths have lower energy photons.

Do all wavelengths travel at same speed in a vacumm and carry the same energy per photon?
Yes, all wavelengths of electromagnetic radiation, including visible light, radio waves, and X-rays, travel at the same speed in a vacuum, which is the speed of light (~3.00 x 10^8 m/s). However, different wavelengths carry different amounts of energy per photon, with shorter wavelengths (like gamma rays) carrying more energy per photon than longer wavelengths (like radio waves).
Could an atom emit one photon of blue light after absorbing only one photon of red light?
No, an atom typically emits photons of the same or lower energy than the absorbed photons. In this case, a red photon has lower energy than a blue photon, so it's not possible for an atom to absorb a red photon and emit a blue photon.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of re-emitted light in a transparent material is the same as the frequency of the light that stimulates its re-emission. This is due to the conservation of energy principle, where the energy of the absorbed photon is re-emitted as a photon of the same frequency.
What is the difference between light energy and radio wave energy?
Light energy is electromagnetic radiation that is visible to the human eye, with a wavelength range from about 400 to 700 nanometers. Radio wave energy, on the other hand, has much longer wavelengths and is used for communication and broadcasting purposes. Both types of energy travel as electromagnetic waves, but they differ in wavelength and how they are utilized.
Does wavelengths that make up the electromagnetic spectrum each have the same amount of energy true?
No, wavelengths in the electromagnetic spectrum do not each have the same amount of energy. The energy of a wave is directly proportional to its frequency, so shorter wavelengths (higher frequency) have more energy than longer wavelengths (lower frequency).
Do all wavelengths travel at same speed in a vacumm and carry the same energy per photon?
Yes, all wavelengths of electromagnetic radiation, including visible light, radio waves, and X-rays, travel at the same speed in a vacuum, which is the speed of light (~3.00 x 10^8 m/s). However, different wavelengths carry different amounts of energy per photon, with shorter wavelengths (like gamma rays) carrying more energy per photon than longer wavelengths (like radio waves).
How does the energy of three photons of blue light compare with that of one photon of blue light from the same source?
The energy of three photons of blue light would be three times that of one photon of blue light from the same source. This is because the energy of a photon is directly proportional to its frequency, and blue light photons have a higher frequency than red light photons.
Photo energy is the same for all wavelengths of light?
False
If a certain fluorescing dye was2 emit a photon with an energy of 4.1x10-19J would this a suitable candidate for a light stick would this photon then be the same as the photon of a hydrogen atom?
no
Could an atom emit one photon of blue light after absorbing only one photon of red light?
No, an atom typically emits photons of the same or lower energy than the absorbed photons. In this case, a red photon has lower energy than a blue photon, so it's not possible for an atom to absorb a red photon and emit a blue photon.
Are protons and photons the same thing?
No. A proton is a part of an atom, while a photon is a tiny bundle of light energy (or light particle).
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron
What change occurs with the atom when it is emitting light?
When an atom emits light, an electron in the atom transitions from a higher energy state to a lower energy state. This transition releases energy in the form of a photon of light. The atom remains the same element before and after emitting light.
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.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of re-emitted light in a transparent material is the same as the frequency of the light that stimulates its re-emission. This is due to the conservation of energy principle, where the energy of the absorbed photon is re-emitted as a photon of the same frequency.

Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
