Detailed Solution

Concept- The radiations in the EM spectrum having shorter wavelength and longer wavelength are gamma rays and radio waves respectively. The range of frequencies and wavelengths that make up electromagnetic radiation is known as the electromagnetic spectrum. It covers a wide range of photon energy and wavelengths. All electromagnetic radiations are grouped in the electromagnetic spectrum by frequency and wavelength.
Every electromagnetic beam in the electromagnetic spectrum is categorised according to its wavelength, as is well known. Gamma rays have a shorter wavelength than radio waves, which have a longer wavelength. Radios, mobile phones, and televisions all employ radio waves as a form of communication. Cancerous cells can be killed with gamma rays.
Hence, the answer is gamma rays and radio waves.
