Energy of Photon = Planck's constant x speed of light / wavelength
= 6.63 x 10-34 x 3 x 108 / 1050 x 10-9
= 1.89 x 10-19 Joules = 1.89 x 10-19 / 1.6 x 10-19 = 1.181 eV

What is the wavelength of a photon that has three times as much energy as that of a photon whose wavelength is 779 nm?
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
How much energy does a 9 x 10-8 m wavelength photon have?
2.21x10-18j
The longer the wavelength of light?
The longer the wavelength of light, the smaller its frequency, and the less energy there is for every photon.
A packet of energy that carries a quantum of energy?
Packet of energy refers to a quantized or definite amount of energy carried by a particle. This packet energy or lumps of energy depends on the wavelength which can be found from Planck's formula E=hf. This is the idea originally provided by Max Planck to explain Black Body Radiation and to solve Ultra-violate catastrophe which later on came out to be the inception of Quantum Mechanics.
Light energy is proof of which Conservation Law?
I am not sure how much of a proof this is; but light energy is involved both in conservation of energy, and in conservation of momentum. A photon has both energy and momentum.I am not sure how much of a proof this is; but light energy is involved both in conservation of energy, and in conservation of momentum.

How much energy does a 9x10 wavelength photon have?
2.21•10^-18 J
Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?
Energy per photon is proportional to frequency. That tells us that it's alsoinversely proportional to wavelength.So if Photon-A has wavelength of 400-nm, then wavelength of Photon-Bwith twice as much energy is 200-nm .
How much energy does a 9 x 10-8 m wavelength photon have?
2.21x10-18j
How much more energetic is a 720nm wavelength than a 520?
-- I have to assume that the '520' figure is also a wavelength in nm.-- The energy of a photon is proportional to its frequency. That also meansthat the energy is inversely proportional to its wavelength. So the photonwith the greater wavelength has less energy.-- 720/520 = 1.385The shorter-wave photon has 38.5% more energy than the longer-wave one.-- 520/720 = 0.722The longer wave photon has 72.2% as much energy as the shorter-wave one has.

An electron requires 4.4 x 10-19 J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
450 nm
How much energy is in 1 mol of an x-ray photon with a wavelength of .180 nm?
6.65X10^5 kj/mol
Does Light photon has more energy than x-ray photon?
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.
An electron requires 4 x 10-17 J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
4.8 - 5.2 nm
The longer the wavelength of light?
The longer the wavelength of light, the smaller its frequency, and the less energy there is for every photon.
An electron requires 4.4 x 10 to the negative 19th power J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
440 - 460 nm
