How much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
548kJ
Why is radiation with shortest wavelength the most powerful?
In our Universe, EM radiation can only come in discrete chunks called "photons." The energy of each individual photon depends on the frequency of the EM radiation. Frequency depends on wavelength (or vice-versa): the shorter the wavelength, the higher the frequency. Thus, short wavelength photons have more energy. That's just how our Universe operates, whether or not we like it.
Which color has the least amount of energy per photon?
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.
Why is there no substance that convert visible light to UV?
UV photons have more energy (less wavelength, higher frequency) than visible light photons. It is possible to convert photons to ones with less enery, but not the opposite.
How do you calculate the energy content of photons in moles?
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).
How much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
548kJ
How do you calculate photon wavelength with only the energy of the photons?
Photon Energy E=hf = hc/w thus wavelength w= hc/E or the wavelength is hc divided by the energy of the photon or w= .2 e-24 Joule meter/Photon Energy.
How does the amount of energy in the light changes as the wavelength increases?
The energy of the photons decreases as the wavelength increases
Photons with the highest energy have?
highest frequency / shortest wavelength / same speed as all other photons.
If the detector is capturing 9 107 photons per second at this wavelength what is the total energy of the photons detected in one hour?
You can easily calculate the energy that the photon detects per second by using the relation E=hc/w where E is energy in Joules, h is Planck's constant, c is the speed of light, and w is the wavelength.
Photons with lowest energy have the?
-- longest wavelength -- lowest frequency
How are wavelength frequency and energy are related?
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
What do 2 photons of the same frequency have in common?
Wavelength, energy, color (if visible).
If the energy of 1.00 mole of photons is 346 kJ what is the wavelength of the light?
289nm
Photons with the highest energy have the longest period?
False they have the shortest wavelength (period)
What does light contain?
Light contains energy in the form of the photons of electromagnetic radiation
Which color photons contain the highest energy?
blue
