hey guy can i ask what type ofradiation with wavelength 26pm

    The given data is

    Wavelength =2.6pm   1pm=10^-12m

                          =2.6*10^-12m

    We know that E= hc/

                         v=c/

    Where E =Eneggy of radiation

              h= planck\'s constant =6.6256*10^-34 J.s

               c= Speed of light =2.998*10⁸m/s

   Plug these value in the Eqation

                E= (6.6256*10^-34 J.s*2.998*10⁸m/s) /2.6*10^-12m

                  = 7.6*10^-14 J

                  =7.6*10^-11 kJ

             From the Frequency v=E/h=  7.6*10^-14J/  6.6256*10^-34 J.s

                                                      =1.147*10²⁰s^-1or Hz

          This frequency is belongs to -radiation .
