To determine

The wavelength for the detection of Lyman alpha photon from the host galaxy of the supernova HSTO4, if the redshift of this galaxy is 1.390. The unshifted wavelength of the light from that hot galaxy, which includes Lyman-alpha (Lα) spectral line of hydrogen, is 121.6 nm. Also define the part of magnetic spectrum in which this wavelength lies.
