As the electrical field corresponds to amplitude; so when the frequency decreases, waves broaden and the extent of the change 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.
