Final answer:
To calculate the wavelength when an electron in a hydrogen atom undergoes a transition from n=3 to n=2, we need the radius of the orbit which is not provided. Without additional information, we cannot determine the exact wavelength of the transition.
Step-by-step explanation:
To calculate the wavelength when an electron in a hydrogen atom undergoes a transition from n=3 to n=2, we can use the formula for the wavelength of light emitted or absorbed during an electron transition in the hydrogen atom. This formula is given by:
λ = 2πrn(1/nf2 - 1/ni2)
Where λ is the wavelength, rn is the radius of the orbit, ni is the initial orbit number, and nf is the final orbit number.
Plugging in the values of ni = 3 and nf = 2, we can calculate the wavelength. However, we need the value of rn to proceed further.
Given only the initial and final orbit numbers, we cannot directly calculate the radius. Without additional information, we cannot determine the exact wavelength of the transition.
