Hint: An electromagnetic wave is nothing but it is a wave radiated by an oscillatory charge in which there is varying magnetic field is the source of the electric field. And that varying electric field is the source of the magnetic field. Both fields are perpendicular to each other. These two fields are also perpendicular to the direction of propagating waves.
To solve this question we have to check the electromagnetic spectrum by doing that it will be easy to find the correct one from the option.
Complete answer:
We know what is electromagnetic radiation and electromagnetic spectrum and also what is electromagnetic wave consisting of. An electromagnetic wave formed due to the vibration. That vibration formed between electric field and magnetic field. It is from shortest wavelength to longest wavelength.
Beta rays are high energy radiation produced by the beta disintegration process. And these are not a part of the electromagnetic spectrum. Gamma rays, X-rays, and heat rays are part of the electromagnetic spectrum and thus they are electromagnetic radiation. Gamma rays are formed by the radioactive disintegration of atomic nuclei, nuclear explosion and lightning etc.
Gamma rays have the smallest wavelength and highest energy in the electromagnetic spectrum.
X-rays are high energy electromagnetic radiation. And its wavelength ranges from 10pm to 10nm. Also X-rays are mostly used in the field of medicine that is mainly for fracture checking.
Hence, the correct answer is option B
Note: Beta rays are not electromagnetic radiation, they are high energy outer space particles. And beta rays are really not electromagnetic radiation but it is because they are charged particles when it is formed during beta disintegration. Also electromagnetic rays can’t be deflected by electric and magnetic fields but beta rays can.
