لتوليد موجات كهرومغناطيسيه يتم استخدام دائره تحتوي على
the Poynting vector describes the energy flow
ما هي الأشعة الكهرومغناطيسية؟
the electromagnetic wave must have the following properties: 1 The field pattern travels with speed c speed of light ; 2 At every point within the wave See Liebel, F; Kaur, S; Ruvolo, E; Kollias, N; Southall, M
the electric field strength E equals "c" times the magnetic field strength B; 3 The electric field and the magnetic field are perpendicular to one another and to the direction of travel, or propagation Electricity and Magnetism, 820p 3rd ed

With UVB, the damage to DNA becomes direct, with photochemical formation of pyrimidine dimers.
