@etstudyteam: ● Electromagnetic waves are transverse waves consisting of oscillating electric and magnetic fields that vibrate perpendicular (at 90°) to each other and to the direction of wave propagation. They travel through space, including a vacuum, at the speed of light (approximately m/s), transferring energy without requiring a material medium. Their energy is carried by the oscillating fields, while their frequency determines how rapidly they vibrate and their wavelength represents the distance between two consecutive corresponding points, such as crests. Frequency and wavelength are inversely proportional, meaning higher-frequency waves have shorter wavelengths and vice versa. #etstudy #physics #engineering #ethiopian_education #math
