Which type of electromagnetic radiation has the longest wavelengths? Which type of electromagnetic radiation has the shortest wa
irinina [24]

Answer: Radio waves has the longest wavelength and Gamma rays has the shortage wavelength.

When wavelength increase and frequency decrease it is related to the energy of each type of radiation.

Explanation: The wavelength of Gamma rays is less than 10 pico meter and energy of Gamma rays is greater than 100kev while the wavelength of radiowaves is 100m to 100km and energy is 100ev to 100kev.

Energy is inversely proportional to wavelength so Gamma rays which have shortage wavelength will have highest energy and radio waves which have longest wavelength will have minimum energy

E=hc/wavelength
