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.
Blue light travels faster in crown glass compared to red light.
Light travels slowest in optically dense materials like glass or water due to the increased interaction and greater number of collisions with particles in the material, causing a delay in its propagation speed.
Light travels fastest through air, then glass, and slowest through water. The speed at which light travels through a medium depends on the refractive index of the material, with lower refractive indexes resulting in faster speeds.

Red since red light travels the slowest
Violet light tends to travel the slowest through a glass prism due to its shorter wavelength compared to other colors of visible light. This causes violet light to refract more as it enters and exits the glass, resulting in a slower speed.
Blue light travels faster in crown glass compared to red light.
Light travels slowest in optically dense materials like glass or water due to the increased interaction and greater number of collisions with particles in the material, causing a delay in its propagation speed.

faulty
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.
Sound travels slowest through d) wood. Wood is a solid material and sound waves travel slower in solids compared to liquids and gases like air, glass, and water.
