The first picture likely depicts a transverse wave, with oscillations perpendicular to the wave's direction. The second picture likely represents a longitudinal wave, characterized by oscillations parallel to the wave's direction, such as sound waves.
The first picture likely represents a transverse wave, characterized by oscillations perpendicular to the direction of wave propagation. Examples include electromagnetic waves like light and radio waves.
In contrast, the second picture likely illustrates a longitudinal wave, where oscillations occur parallel to the direction of wave travel.
Sound waves in air and seismic waves are common examples of longitudinal waves.
The distinction lies in particle displacement during the wave's transmission.
Transverse waves exhibit perpendicular displacement, while longitudinal waves involve parallel compression and rarefaction. Recognizing these wave types aids in understanding diverse phenomena in physics, acoustics, and wave mechanics.
