Answer
All these transitions emit infrared electromagnetic radiation.
Work Step by Step
The wavelength of light emitted during transitions in a hydrogen atom can be calculated using the Rydberg equation.
a. For the transition n = 4 → n = 3, the wavelength is 1875 nm.
b. For the transition n = 5 → n = 4, the wavelength is 4051 nm.
c. For the transition n = 5 → n = 3, the wavelength is 1282 nm.
All these transitions emit infrared electromagnetic radiation.
