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
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:
you get:
wavelength= 5.054*10⁻⁷ m

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.
<h3>What is an ideal gas?</h3>An ideal gas is a gas whose behavior can be explained through ideal gas laws. One of them is the combined gas law.
A gas occupies 1.15 L (V₁) at STP (T₁ = 273,15 K and P₁ = 760 mmHg). We can calculate the temperature (T₂) at which V₂ = 1.56 L and P₂ = 650 mmHg, using the combined gas law.
