Identify the characteristics of an electromagnet and mechanical waves
Term | Definition |
---|---|
wave | a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium |
medium | a physical environment in which a phenomena occurs |
mechanical wave | a wave that needs a medium in which to travel |
transverse wave | a wave in which the particles of the medium move parallel to the direction of the wave motion |
longitudinal wave | a wave in which the particles of the medium vibrate perpendicular to the direction of the wave motion |
compression | part of the longitudinal wave where the particles bunch up bunch up close together |
refraction | part of longitudinal wave in which the particles expand and move apart |
electromagnetic wave | a wave that consists of electric and magnetic fields that vibrate at right angles to each other |
