What is the wavelength λ of the photon that has been released by−2.05×10−18 J?
E = hc/wavelength
To find the wavelength (λ) of a photon, you can use the formula:
λ = c / ν
Where:
λ is the wavelength of the photon
c is the speed of light (approximately 3.00 x 10^8 m/s)
ν is the frequency of the photon
In this case, you are given the energy of the photon as -2.05 x 10^-18 J. The energy of a photon can be calculated using the formula:
E = h * ν
Where:
E is the energy of the photon
h is Planck's constant (approximately 6.63 x 10^-34 J·s)
We can rearrange this formula to solve for the frequency (ν):
ν = E / h
Now, we can substitute the given energy (-2.05 x 10^-18 J) into the formula to find the frequency.
ν = (-2.05 x 10^-18 J) / (6.63 x 10^-34 J·s)
By calculating this expression, we find the frequency (ν) of the photon.
Finally, we can substitute the found frequency into the wavelength formula to solve for the wavelength (λ):
λ = (3.00 x 10^8 m/s) / ν
By evaluating this expression, we can find the wavelength (λ) of the photon.
