The entire electromagnetic spectrum travels at the same speed. The speed of light.
Violet travels 1% slower than red does in natural grass.
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.
Light travels slowest through materials with a higher refractive index, such as glass or diamond. This is because the speed of light in a material is inversely proportional to its refractive index.
The phases of matter from fastest to slowest that sound travels through are solids, liquids, and gases. Sound travels fastest through solids because the particles are closer together and can easily transmit vibrations. In liquids, sound travels slower due to the looser arrangement of particles, and in gases, sound travels slowest because the particles are widely spaced.
The slowest point of a projectile's trajectory is at the peak of its curve, where its vertical velocity momentarily reaches zero before changing direction and accelerating back downwards due to the force of gravity.
Violet travels 1% slower than red does in natural grass.

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.
Sound travels slowest through air because the particles in the air are spread apart.

All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
