Calculate the wavelength of a photon having 3.26 x 10^-19 joules of energy
1 answer:
The energy of a photon is given by:
where h is the Planck constant and f is the photon frequency.
We know the energy of the photon,
, so we can rearrange the equation to calculate the frequency of the photon:
And now we can use the following relationship between frequency f, wavelength
and speed of light c to find the wavelength of the photon:
where h is the Planck constant and f is the photon frequency.
We know the energy of the photon,
And now we can use the following relationship between frequency f, wavelength

In this case, volume of the can remains constant. The relationship between pressure and temperature at constant volume is given by:
P/T = Constant
Then
Where
P1 = 40 psi
P2 = ?
T1 = 60°F ≈ 289 K
T2 = 90°F ≈ 305 K (note, 363 K is not right)
Substituting;
P/T = Constant
Then
Where
P1 = 40 psi
P2 = ?
T1 = 60°F ≈ 289 K
T2 = 90°F ≈ 305 K (note, 363 K is not right)
