Why do some photons travel right through the atom unchanged while others are absorbed?
Photons can travel through an atom without being absorbed if they do not have enough energy to interact with the electrons in the atom. However, if a photon has enough energy to match the energy levels of the electrons in the atom, it can be absorbed, causing the electron to move to a higher energy level or be ejected from the atom.
What is a form of electromagnetic energy made up of streams of photons?
Light is a form of electromagnetic energy composed of streams of photons. Photons are the basic unit of light, carrying energy and momentum as they travel.
Do x-rays travel slower than infrared?
No, x-rays travel faster than infrared radiation. X-rays have higher energy and shorter wavelengths, allowing them to travel at the speed of light in a vacuum while infrared radiation has longer wavelengths and travels at a slower speed.
How are photons affected by gravity?
Photons are affected by gravity because they have energy and momentum, which can be influenced by gravitational fields. Gravity can cause photons to change direction or lose energy as they travel through space. This effect is known as gravitational lensing.
Why are the sun's rays electromagnetic?
The sun's rays consist of electromagnetic radiation because the sun emits energy in the form of photons. These photons travel through space as electromagnetic waves, carrying energy that we experience as sunlight.

Do photons have weight?
No, photons do not have weight. Photons are particles, made pure out of energy, which travel at the speed of sound.
In what form does all radiant energy travel through space?
Radiant energy travels through space in the form of electromagnetic waves, specifically as photons. These photons have no mass and move at the speed of light.
Do ultraviolet photons travel at with a greather speed than yellow photons?
No. All photons travel at the speed of light.
How does energy in the form of light photons travel through the many layers of the sun?
Energy in the form of light photons travels through the many layers of the sun by a process called radiation. In the sun's core, nuclear fusion creates high-energy photons that travel outward through the radiative zone, where they bounce around and gradually lose energy. Eventually, the photons reach the convective zone, where they move more freely and reach the sun's surface as visible light.
How do photons that leave the sun travel?
Photons leaving the Sun travel through the vacuum of space at the speed of light in straight lines. They carry energy and heat and can travel vast distances before they are absorbed or scattered by other particles in space.
Which travels fastest through a medium a photon atom sound or electron?
A photon travels fastest through a medium, followed by sound, then electrons. Photons travel at the speed of light in a vacuum, which is faster than the speed of sound or electrons in a medium. Sound travels at a much slower speed than light, while electrons generally move at speeds that are significantly slower than both photons and sound waves.
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.
