Hey mate here is ur ans
electro magnetic waves :-
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves EM waves travel with a constant velocity of 3.00 x 108 ms-1 in vacuum. They are deflected neither by the electric field, nor by the magnetic field. The highest point of a wave is known as 'crest', whereas the lowest point is known as 'trough'. Electromagnetic waves can be split into a range of frequencies This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc. They are deflected neither by the electric field, nor by the magnetic field. However, they are capable of showing interference or diffraction They are also perpendicular to the direction of the EM wave.
An electromagnetic wave can travel through anything - be it air, a solid material or vacuum. It does not need a medium to propagate or travel from one place to another. Mechanical waves (like sound waves or water waves), on the other hand, need a medium to travel. EM waves are 'transverse' waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves). EM waves are composed of oscillating magnetic and electric fields.
hopes it helps uh ❗ ❗ ☺
i dont know aunty but if it is helpful to u mark me as brainliest
