The equation for photon energy, E, is E=hc/λ
Leni [432]

Answer:

The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m

Explanation:

The wavelength is defined for every periodic wave, that is, for the type of wave that repeats itself with exactly the same shape every given interval of time. It is the distance between two points from which the wave repeats.

Radiation is the emission, propagation and transfer of energy in any medium in the form of electromagnetic waves or particles.

The energy carried by electromagnetic radiation travels by waves. This energy is transmitted grouped in small "quanta" of energy called photons. The energy of a photon is measured in Joules (J) and is

E=\frac{h*c}{wavelength}

Being:

  • E=3.92×10⁻¹⁹ J
  • h= 6.626×10⁻³⁴ J⋅s (Planck's constant)
  • c = 2.99×10⁸ m/s (the speed of light)
  • wavelength=?

and replacing:

3.92*10^{-19}J =\frac{6.626*10^{-34}J.s*2.99*10^{8}\frac{m}{s}   }{wavelength}

you get:

wavelength =\frac{6.626*10^{-34}J.s*2.99*10^{8}\frac{m}{s}   }{3.92*10^{-19}J}

wavelength= 5.054*10⁻⁷ m

<u><em>The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m</em></u>

The greatest amount of energy released per gram of reactants occurs during a(1) redox reaction
masya89 [10]

Answer : The correct option is, (2) Fission reaction.

Explanation :

  • Fission reaction : This is a type of nuclear reaction in which the splitting of bigger nuclei into two smaller nuclei takes place. During this process, the large amount of energy is released.
  • Redox reaction : This is an oxidation-reduction reaction in which the electrons transferred between the two molecules.
  • Substitution reaction : In this reaction, one functional group is replaced by the another functional group in a chemical compound.
  • Neutralization reaction : In this reaction, the acid and base react to give water and a salt.

Redox reaction, substitution reaction and neutralization reaction are the chemical reactions in which the heat releases when the chemical bonds are breaking and forming.

Therefore, the greatest amount of energy released per gram of reactants occurs during the fission reaction.
