Electromagnetic waves vary in frequency, wavelength, and energy. These properties determine the type of electromagnetic wave, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of electromagnetic wave has unique characteristics and uses.
Electromagnetic waves.
Ultrasonic waves are mechanical waves that require a medium (such as air, water, or solids) to travel through, unlike electromagnetic waves which can propagate through a vacuum. Ultrasonic waves involve the vibrations of particles in the medium, whereas electromagnetic waves involve oscillating electric and magnetic fields.
Sound waves are not a type of electromagnetic wave. Sound waves are mechanical vibrations that require a medium, such as air or water, to propagate, whereas electromagnetic waves can travel through a vacuum.
Electromagnetic waves are a combination of electric and magnetic fields that propagate through space. They carry energy and can vary in strength depending on factors like frequency and amplitude. On the other hand, "regular" magnetic waves may refer to static magnetic fields which do not propagate like waves. It is not accurate to compare the strength of electromagnetic waves with regular magnetic waves as they represent different phenomena.
Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).
