What in tarnation is a "mole" of photons ???
Don't you have to know the atomic number or the molecular weight of an element or compound
in order to know the size of a mole ?
Do you happen to know the atomic number or the molecular weight of a Photon ???
I don't think Avogadro was talking about photons.
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
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.
High-energy photons correspond to short-wavelength light while low-energy photons correspond to long-wavelength light. In short, the answer is red. For short-wavelengths (high energy photons) it would appear blue.
Yes, due to the energy of photons/electromagnetic particles being determined by the equations below: E= hv=hc(1/v)= hc/wavelength. Where E= energy, v= frequency in Hz, h= Planck's constant, c= speed of light Electrons have a very short wavelength, and a very high frequency, thus they have much more energy than a beam of light.
To calculate the number of photons, you need the formula E=hf where h is Planck's constant with a value of 6.63*10^-34Js and f should be given. If f isn't given, then use the formula C = f * wavelength. Rearrange this formula by using the wavelength given and the C, speed of light, which is 3*10^8. You should get C/wavelength = f, which will then be placed into E=hf => answer. What you also need is the Intensity. This way you obtain the photon flux as: I/E (i.e. the number of photons per unit area and unit time).
When the wavelength of light is doubled, the energy of photons decreases by half.
The energy of the photons decreases as the wavelength increases
No, violet light carries more energy than red light. Violet light has a shorter wavelength and higher frequency, which corresponds to higher energy photons, while red light has a longer wavelength and lower energy photons.
Red light has a lower amount of energy than blue light. This is because red light has a longer wavelength, which corresponds to lower energy photons, while blue light has a shorter wavelength and higher energy photons.
Color wavelength and photon energy are inversely related. This means that as the wavelength of light decreases and the frequency increases, the energy of the photons also increases. Shorter wavelengths correspond to higher energy photons, such as in the case of ultraviolet light having higher energy than visible light.
Photons (energy packets of light)
No, the speed of light in a vacuum is constant for all photons regardless of their energy. Higher energy photons have a higher frequency and shorter wavelength, but they still travel at the speed of light.
To find the wavelength of the light, you can use the energy-wavelength relationship given by E = hc/λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Rearrange the formula to solve for λ: λ = hc/E. Substitute the values for h, c, and the energy of 1.00 mole of photons to calculate the wavelength.
To calculate the number of photons, you can use the formula: Energy of 1 photon = hc / λ where h is Planck's constant, c is the speed of light, and λ is the wavelength. From this, you can determine the energy of one photon of light with a 4000 pm wavelength and then calculate the number of photons required to provide 1 Joule of energy.
Energy of light photons is related to frequency as Energy = h(Planck's constant)* frequency Frequency = velocity of wave / wavelength So energy = h * velocity of the wave / wavelength
They are inversely proportional or relationship to each other.
Shortest wavelength means the highest frequency, meaning the photons have the highest energy. That is color violet. The violet light colors the skin brown. Red light with lower energy photons cannot do that.
