Do all wavelengths travel at same speed in a vacumm and carry the same energy per photon?
False
What is Light waves?
Is the direction of the wave of the light energy in the same path of the photon.
How do you find wavelength if you've been given the energy?
The easiest way would be to find a descriptive article on the internet that shows the visible colors spread out with some wavelengths labeled. There, you can find the approximate wavelengths for light of various colors. If you don't know the color of the light, then in order to find its wavelength, you'd need to know either its frequency or the energy of a photon (quantum). Energy of a photon = h f h = Planck's Konstant = about 6.63 x 10-34 joule-second f = frequency of the light wave or photon But the frequency is (speed of light)/(wavelength) so, Energy = h c/wavelength . If you know either the energy of the photon or its frequency, you can use this stuff to find its wavelength. In this discussion, I've toggled back and forth a few times between the frequency/wavelength of the quantum and the frequency/wavelength of the light wave. Don't worry. They're the same.
Is light made of photons?
Yes, but at the same time it is a wave too. Light is the borderline between energy and matter.
Could you emit the same amount of light energy per second which must emit more photons per second a source of red light or a source of blue light?
Red light has less energy per photon than blue light, so to get the same energy we would need more red photons.

False

Photo energy is the same for all wavelengths of light?
False
How does the energy of three photons of blue light compare with that of one photon of blue light from the same source?
If the color (frequency, wavelength) of each is the same, then each photon carries the same amount of energy. Three of them carry three times the energy that one of them carries.
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

Yes, but at the same time it is a wave too. Light is the borderline between energy and matter.
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
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.
