Answer :
As the electrical field corresponds to amplitude; so when the frequency decreases, waves broaden and the extent of the change decreases.
What happens when frequency of electromagnetic radiation decreases?
When the frequency decreases, then the wavelength gets longer. There are two types of waves: mechanical and electromagnetic. Mechanical waves like sound, ocean, seismic, or earthquake travel through a solid, liquid, or gas medium whereas electromagnetic waves travel through a medium or a vacuum.
The energy equation is given as, E = hν, where E represents energy, h is Planck's constant whose value is 6.626 x 10 -34 J.s and v represents frequency. The energy equation is direct relationship between frequency and energy. As frequency increases, energy. also increases.
