Waves travel slowest in mediums that offer more resistance to their propagation, such as solid materials like rock or metal. The speed of waves is determined by the medium's density and elasticity - the denser and less elastic the medium, the slower the waves will travel.
Mechanical waves travel slowest in gases, such as air. This is because gases have low density and low rigidity, leading to slower propagation of waves compared to liquids and solids.
Sound waves require a medium, such as air or water, to propagate because they rely on the vibration of molecules. In a vacuum, there are no molecules for the sound waves to travel through, so they cannot propagate, resulting in the absence of sound.
Planets travel slowest at their aphelion – the point in their orbit farthest from the sun. This is when they are moving at their slowest speed due to the effect of gravity.
In matter, electromagnetic waves travel slowest in solids, faster in liquids, and fastest in gases. This speed variation is due to the differences in density and the interactions between the particles in each state of matter.
Light travels slower in oil than in a vacuum because oil has a higher refractive index than a vacuum, which causes light to slow down as it moves through the medium. The denser the medium, the slower light will travel.
The slowest travel day of the week for most people is typically Sunday.
Light travels slowest in a medium with the highest refractive index, such as glass or diamond. This causes light to bend and slow down as it enters the material, leading to a decrease in its speed compared to its speed in a vacuum.

Sound travels through a medium such as air, water, or solids. It moves as a series of compression waves that cause particles in the medium to vibrate, transmitting energy from one point to another. The speed of sound varies depending on the medium, with it traveling fastest in solids and slowest in gases like air.
Sound travels slowest through air because the particles in the air are spread apart.
Light travels slowest in a medium with a high refractive index, such as glass or water. This is because light is absorbed and re-emitted by atoms in the medium, causing it to slow down compared to its speed in a vacuum.
