Question

The wavelength of the characteristic x-ray line emitted by a hydrogen like element is 0.32 . The wavelength of k line emitted by the same element will be

Answer 1

Answer:

Explanation:

Light of wavelength ‘λ’ which is less than threshold wavelength is incident on a photosensitivematerial. If incident wavelength is decreased so that emitted photoelectrons are moving withsame velocity then stopping potential will
