Answer (1)
Answer:Here are the properties of Electromagnetic (EM) Waves, categorized for easy reference:*1. Composition Categories*- Electric field component (E)- Magnetic field component (B)*2. Direction of Propagation*- Transverse waves (perpendicular to direction of propagation)- Longitudinal waves (parallel to direction of propagation), but only in plasma*3. Medium in which it can propagate*- Vacuum (no medium)- Air- Water- Solid objects (e.g., glass, metal)- Plasma*4. Speed*- Constant in vacuum: approximately 299,792,458 m/s (c)- Variable in medium: depends on permittivity and permeability*5. Wavelength and Frequency*- Wavelength (λ): distance between consecutive peaks or troughs- Frequency (f): number of oscillations per second (Hz)- Relationship: c = λ × f*6. Interaction with matter*- Reflection- Refraction- Diffraction- Absorption- Transmission- ScatteringAdditional properties:- Polarization- Intensity (power per unit area)- PhaseTypes of EM Waves, listed by increasing frequency:1. Radio waves2. Microwaves3. Infrared (IR) radiation4. Visible light5. Ultraviolet (UV) radiation6. X-rays7. Gamma raysThese properties and categories help us understand the behavior and characteristics of EM waves, essential for various applications in physics, engineering, and technology.
