Hint: A wave is a disruption in a medium that maintains the energy without the total motion of particles. The wavelength of a wave is the length between two consecutive crests or troughs in a wave. The crest and trough are the points at which there is the highest upward displacement and downward displacement respectively in a wave cycle.
Complete Step by Step Solution:
James Maxwell (1870) was the foremost to produce a thorough description about the interaction between the charged bodies and the conduct of electrical and magnetic fields on a macroscopic level. He indicated that when electrically charged particle motions under acceleration, rotating electrical and magnetic fields are created and transmitted. These fields are passed on in the form of waves are known as electromagnetic waves or electromagnetic radiation.
Various kinds of units are utilised for electromagnetic radiation. These radiations have different properties, namely, frequency and wavelength. Frequency is the no.of waves that enter through a provided point in one second. The SI unit is hertz (Hz). Wavelength has the units of length (m).
This frequency range is split up into different bands, starting with electromagnetic waves of low frequency or long wavelength at the end of the spectrum with radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency or short wavelength at the opposite end.
There are numerous varieties of electromagnetic radiation that vary from one another in wavelength (or frequency). These are called the electromagnetic spectrum. Various areas of the spectrum are determined by different names. For example, the radio frequency region around 106 Hz, is utilised for broadcasting, microwave region around 1010 Hz is utilised for radar and the infrared region around 1013 Hz is utilised for heating. The little part around 1015 Hz, is called visible light.
Here in this question, we have been asked about the wavelength of radio waves. The wavelength of radio waves is greater than microwaves.
So, option B is correct.
Note: It is to be noted that Gibbs free energy tells us the maximum work done in a system keeping the pressure and temperature constant. It is symbolically represented by the letter G. At equilibrium, the \[\Delta G\] value is zero.
