low density.
Yes, they are exactly analogous and corresponding.
The lowest point on a transverse wave is called the trough
The distance between one trough and the next trough in a transverse wave is equal to one full wavelength of the wave.
No, an electromagnetic wave is NOT a compressional wave. An electromagnetic wave is best described as a transverse wave. Remember that in a compressional wave, the energy moves parallel to the medium of the wave, while in a transverse wave, the energy moves perpendicular to the medium.
To measure the wavelength of a transverse wave, you would measure the distance from a point on one wave to the corresponding point on the next wave, such as from peak to peak or trough to trough. This distance represents one full wavelength of the wave.

A sound wave is a compressional wave, which means the particles in the medium vibrate parallel to the direction of the wave propagation. This compression and rarefaction of particles create the variations in pressure that we perceive as sound.
In a compressional wave, the density of the medium varies periodically as the wave travels through it. This variation corresponds to the peaks and troughs in a transverse wave, where the denser regions represent the peaks of compression and the less dense regions represent the troughs of rarefaction. However, in a compressional wave, this density variation occurs in the same direction as the wave propagation, whereas in a transverse wave it occurs perpendicular to the direction of wave propagation.
An electromagnetic wave is a transverse wave because the electric and magnetic fields oscillate perpendicular to the direction of wave propagation. This means that the vibrations of the wave are perpendicular to the direction in which the wave is moving.
In a transverse wave, the trough represents the lowest point where the displacement of the wave is at its minimum value. This is because the trough corresponds to the region of the wave where the particles are at their lowest point of oscillation, moving in opposite direction to the direction of wave propagation.
No, a sound wave is a compressional wave.
