Answer:
The first one is Longitudinal
The second one Transverse
The third one is Longitudinal
The fourth one is Transverse
Explanation:
Transverse Waves:
Waves can have different shapes. The differences in wave shapes are due to the direction of the disturbance as the wave travels. Waves in which the disturbance moves at right angles to the direction of the wave are called transverse waves. The string of beads shown in the simulation is a transverse wave. In transverse waves, the disturbance moves up and down as the waves move horizontally. Seismic waves are also transverse waves.
Longitudinal Waves:
Waves in which the disturbance moves in the same direction as the waves are called longitudinal waves. Longitudinal waves are also known as compression waves.
Sound waves are longitudinal. In a sound wave, air molecules collide with each other in the direction of the wave’s movement. If we compress one end of a spring and let go, the coil moves from left to right as the wave travels. So, a wave that moves through a spring this way is also a compression wave.
Water waves are a combination of transverse and longitudinal waves. As a result, the water molecules travel in an oval-shaped path.
