Hello Mate,
These are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. Some electromagnetic waves are generally harmless. ... Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency....
Hope this helps you
What are electromagnetic waves ?
→ Electromagnetic waves are waves that are created as a result of vibrations between an electric field and a magnetic field.
→ EM waves are composed of oscillating magnetic and electric fields.
What are the properties of electromagnetic waves ?
→ Electromagnetic waves have properties of speed, wavelength, and frequency.
→ An accelerated charge produces a time-varying magnetic field which in turn produces a time-varying electric field. Thus, electromagnetic wave consists of sinusoidal time-varying electric and magnetic fields and both the fields are perpendicular to each other.
