Question

Calculate the energy of photons, in joules per photon and kilojoules per mole, for 1000-kilocycle broadcast-band radio waves. (one kilocycle is a frequency of a thousand hertz). What is the wavelength of such photons? How does the energy compare with that for a carbon-carbon single bond?

Answer 1

I Ans frequency (U) = 1000 kilocycle I kilo cycle = 10²42 low kilo cycle = 106 Hz Relation blw wave length & frequency . C= do sc= Velocity of light = 3xldo misec de e d= 3x108 da wave length 106 d= 3x10²m AS : Energy of Photon E= pant hc s h= plank's Constant = 6.62x107472 E = 6.62x10 34 x 30/08 3x 102 E = 6.62 x 10-20 , E= 39.88105 byl mall C-c single bond energy (Ec) = 348 kg /mel TE JEJ
