Electromagnetic waves always travel at whatever the speed of light is
in the material they're traveling through. That's the highest possible speed
for anything moving in that particular material, so it can't be called "slow".
S-waves are slower than P-waves, which are the fastest seismic waves. S-waves are shear waves that move in a back-and-forth motion, causing particles to move perpendicular to the direction of wave propagation.
bend towards the normal and slow down due to the increase in optical density.
Different types of waves move in different patterns. Ocean waves move in a circular pattern while sound waves move in a sinusoidal pattern.
The large slow brain waves associated with sleep are called delta waves. These waves are typically observed during deep sleep stages.
When light waves move from empty space into the Earth's atmosphere, they will refract or bend due to the change in the medium's density. The different gases in the atmosphere will cause the light waves to slow down and change direction, leading to effects like dispersion, scattering, and absorption.

they move slow
Waves slow down when they move from one medium to another with a different wave speed. This can happen at boundaries between materials of different densities, such as air to water or water to glass. The change in speed is due to the change in the wave's frequency and wavelength as it enters the new medium.
Slow waves are a type of electrical activity that occurs within the brain during deep sleep. These waves are characterized by their slow frequency and high amplitude, and are believed to play a role in consolidating memories and promoting overall brain health. Monitoring slow waves can provide insights into the quality of sleep and brain function.
Delta waves
Microwaves ARE radio waves, and they move with the same speed as all other electromagnetic waves.
Electromagnetic waves propagate (move) with their own energy.
