How many meters will a photon of light energy travel in one nanosecond?

About 0.3 meters in a vacuum. Divide that by 1.0003 to get the distance in meters per nanosecond through air. Divide by 1.5 for glass.

Do all wavelengths travel at same speed in a vacumm and carry the same energy per photon?
False
How do light rays travel from the object to the image?
Photon light ray
The transfer of energy that does not require matter is?
A photon wave (anything in the light spectrum, visible or not) is able to travel through a vacuum (no medium/no matter). This is in correspondence with Einstein's theories of special relativity. A photon is not an easy thing to explain, but I would describe it a a physical particle with no mass, and is therefore not matter.
What is the speed of a photon of red light if its frequency is 4.3 x 1014 Hz?
All photons have the same speed in a vacuum, no matter what their frequency. They all travel at the speed of light: 299,792,458 meters per second.
How does the speed of a photon compare to the speed of an EM wave?
Wave length of gamma rays is 10 raised to the power of minus 12. It means that you have 10 raised to 12 waves in case of gamma rays/ meter. Wave length of radio wave is 10 raised to 3. So there is difference of '12' zeros between both of them. But the speed of electromagnetic wave is about 300,000,000 meters/ second. It means that photon travels about 300,000,000 meters/second. So the actual distance traveled by photon in case of radio wave is little more than 300,000,000 meters. So in case of gamma rays the distance traveled by photon is 1,000,000,000,000 *1000 = 1000,000,000,000,000 times that of radio wave per second.
Why does a photon travel?
because it has energy. but where did it come from? Not known yet
How does energy from the sun travel to the planets?
Energy from our Sun travels to the planets through space in the form of electromagnetic radiation, the carrier of which energy is the photon.
Do all wavelengths travel at same speed in a vacumm and carry the same energy per photon?
False
How many inches does electricity travel in a nanosecond?
11.8 inches
How does light energy travel?
299,792,458 meters/second
How fast does light energy travel?
299,792,458 meters/second
How much time does it take light to travel one foot?
One nanosecond.
How many seconds equal 1 nanosecond?
1 nanosecond = 10-9 sec = 0.000000001 sec = 1 billionth of a sec. (Roughly the time it takes light/radio to travel one foot.)
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 far does light travel in a single nanosecond?
1 billionth of a second 1X10^-10
What type of energy is useful in light?
Light is energy. Light is made of massless particles called photons that travel at the speed of light. Photons at a given frequency carry energy equal to the Planck constant times the photon's frequency.
What are the frequency and wavelength of the photon?
c = wavelength X frequency, where c is the speed of light, which is 299,792,458 m/s. So you need the wavelength of the photon. Then you divide c/wavelength and the result will be the frequency.
