JEE Advanced 2023 Chemistry question

For , a transition takes place from the orbit of radius 105.8 pm to the orbit of radius 26.45 pm. The wavelength (in nm) of the emitted photon during the transition is . [Use: Bohr radius, a = 52.9 pm; Rydberg constant, = 2.2 × 10 J; Planck's constant, h = 6.6 × 10 J s; Speed of light, c = 3 × 10 m s]
