Question

16. Given: h = 6.6 x 10-34 J-sec En = -2.18 x 10-18 J/n2 (note: Joule = kg-m2
/sec2
)

c = 3.0 x 108 m/sec mass electron (me) = 9.1 x 10-31 kg

Determine the wavelength and frequency for the radiation emitted when a hydrogen electron excited to the
4th energy level decays to the ground state. What type of electromagnetic radiation is this?

Answer 1

it lies in ultravoilet radiation because wavelength of this lies in this region
