An example of a transverse wave is a wave on a string when it is plucked or shaken. In this type of wave, the particles of the medium move perpendicular (sideways) to the direction of the wave propagation. This causes crests and troughs to form as the wave travels along the medium.
Sound wave is an example of a purely longitudinal wave. In a sound wave, the particles of the medium vibrate in the same direction as the wave is moving, creating compressions and rarefactions as the wave travels through the medium.
The example provided is an example of a mechanical wave, specifically a surface wave, which occurs at the interface between two different media, in this case, air and water.
The disturbance that travels through a medium as a compressional wave is called a longitudinal wave. In this type of wave, the particles of the medium move parallel to the direction of the wave's energy propagation. Sound waves are a common example of longitudinal waves.
A guitar string vibrating at its fundamental frequency (first harmonic) is an example of a common standing wave. The fixed ends of the guitar string create nodes, and the string vibrates in segments with antinodes in between.
how was the wave of U.S immigration in the late 1800s different from the previous wave of immigration in the mid-1800s?
Mariel Boat Lift was the second wave of immigration. The third wave occurred during Cuba's Special Period in 1994 and they are called Balseros.

"Old" immigrants were from western Europe, and "new" immigrants were from eastern and southern Europe.
The power to tax and control immigration is an example of reserved power.
