This study guide covers electromagnetic (EM) waves, including their key characteristics (transverse waves, perpendicular electric and magnetic fields, constant speed of light), the EM spectrum (radio waves, microwaves, infrared, visible light â ROYGBV, ultraviolet, X-rays, gamma rays), and the relationship between wavelength, frequency, and energy (). It also discusses EM wave applications, high vs. low frequency waves, wave representations (sine wave, transverse wave model), and provides practice problems with solutions focusing on calculations and conceptual understanding. Finally, it offers exam tips for success.

Question 1 of 8
In an electromagnetic wave, how are the electric and magnetic fields oriented relative to each other and to the direction of the wave's propagation? đ§
The electric and magnetic fields are parallel to each other and to the direction of propagation
The electric and magnetic fields are perpendicular to each other but parallel to the direction of propagation
The electric and magnetic fields are parallel to each other but perpendicular to the direction of propagation
The electric and magnetic fields are perpendicular to each other and to the direction of propagation
