Question

In the order of increasing frequency, the electromagnetic spectrum may be arranged as-

A.)Gamma rays, X-rays, visible light, radio waves
B.)X-rays, gamma rays, visible light, radio waves
C.)Radio waves, visible light, X-rays, gamma rays
D.)Radio waves, visible light, gamma rays, X-rays

Answer 1

Hint: The only known component of electromagnetic radiation has been visible light for much of the world. Try to recall the different waves in the spectrum along with their frequency. It will help in solving the question.

Complete answer:
Electromagnetic spectrum, all distribution by frequency or wavelength, of electromagnetic radiation. Although all electromagnetic waves travel in a vacuum near the speed of light, they do so at various speeds, wavelengths and photon energies. The electromagnetic spectrum consisted entirely of many subranges, commonly referred to as portions such as visible light or ultraviolet radiation. This includes all electromagnetic radiation. The various sections have specific names depending on different individual variations with respect to the production, propagation and absorption of the waves and also on their different functional implementations. The borders of such adjacent parts are not agreed exactly, and so the ranges continue to overlap.

Some of the radio signals (for example, broadcast radio and Television, microwaves, radar), infrared radiation, visible light , ultraviolet radiation, X-rays and gamma rays, are part of the whole electromagnetic range from the lowest to the maximum frequency (longest to shortest wavelength). Almost all electromagnetic radiation frequencies and wavelengths can be used for spectroscopy.

A spectrum is not just a certain set of values but can vary throughout a continuum without steps. The word was used in optics for the first time in science, to describe the rainbow of colors in visible light after a prism. As the scientific knowledge of light developed, it applied to the whole electromagnetic spectrum.

Gamma rays have the highest frequency.

Electro-magnetic field is a set containing all waves separated by frequency and wavelength. As shown in the picture, there are: radio waves, visible light, rays and Gamma rays. The frequency is growing.

Hence, option C is the correct option.

Note: A technique called spectroscopy can also be used in most frequency bands above to separate physical waves of various frequencies and produce a spectrum that displays the component frequencies. The relationships of electromagnetic waves and matter were analyzed through spectroscopy. The electromagnetic radiation describes other technological uses.
