Ultraviolet radiations cause cancer.
em wave is generated by photons which emitter the energy in the form of light
The frequency of an electromagnetic (EM) wave is directly proportional to its energy. This means that as the frequency of the EM wave increases, so does its energy. Conversely, a decrease in frequency leads to a decrease in energy of the EM wave.
radio wave
EM waves stand for Electromagnetic waves.
The energy of an electromagnetic (EM) wave is determined by its frequency and amplitude. The higher the frequency, the higher the energy of the wave. Additionally, the amplitude of the wave also plays a role in its energy content.
They're the same. EM stands for electromagnetic.
visible light
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
No, it's not. EM wave is a single unit, and it cannot exist without ether of components (electric, magnetic).
Sound is a mechanical wave, not an electromagnetic wave.
wave
The wavelength of an electromagnetic (EM) wave is inversely proportional to its energy - shorter wavelengths correspond to higher energy, and longer wavelengths correspond to lower energy. This phenomenon is described by the equation E = hν, where E is the energy of the EM wave, h is Planck's constant, and ν is the frequency of the wave.
