Step 1

The energy of a photon of a radiation is expressed as: help_outlineImage Transcriptioncloseh c E Where, E energy of a photon Planck's constant = 6.626 x 1034 J/s h c speed of light = 3 x 108 m/s A = wavelength fullscreen
Step 2

And the energy of one mole of the radiation = 6.022 × 1023 × energy of a photon

Given,

We know that, 1 km = 1000 m

⸫ wavelength in m = 0.250 × 1000 m = 250 m

The energy of one photon of this radiowave radiation can be calculated as: help_outlineImage Transcriptioncloseh c Е- λ 6.626 х10-34 ]/sx 3x108 m/s Е- 250 m E 3D 7.95 х 10-28 J fullscreen
Step 3

The energy of one mole of this radiowave&n... help_outlineImage TranscriptioncloseE 6.022 x 1023 x energy of a photon E 6.022 x 1023 x 7.95 x 10-28 J E 4.79 x 104 J fullscreen
