Question
What transition energy corresponds to an absorption line at 460 nm?A.4.45 𝑥x 10-19 JB.4.32 𝑥x 10-19 JC.6.52 𝑥x 10-19 JD.2.31 𝑥x 10-19 J
Solution
To find the transition energy that corresponds to an absorption line at 460 nm, we can use the formula for the energy of a photon:
E = hc/λ
where: E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J*s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength of the light.
First, we need to convert the wavelength from nanometers to meters:
460 nm = 460 x 10^-9 m
Then, we can substitute the values into the formula:
E = (6.626 x 10^-34 J*s) * (3.00 x 10^8 m/s) / (460 x 10^-9 m) E = 4.32 x 10^-19 J
So, the transition energy that corresponds to an absorption line at 460 nm is 4.32 x 10^-19 J. Therefore, the correct answer is B. 4.32 x 10^-19 J.
