Light rays can travel through air, vacuum, and transparent materials such as glass or water. These materials allow the propagation of light by allowing the rays to pass through with little to no absorption or reflection.
Air, food, and liquid travel through the pharynx.
Light can travel through air, water, and glass. Each of these mediums allows light to pass through due to their transparent properties.
Light can travel through air, water, and glass due to their transparent properties that allow light to pass through with minimal absorption or reflection.
The sun, fire, and light bulbs are three things that give off light and heat. The sun is a natural source of light and heat, fire is created through combustion, and light bulbs produce light and heat through electricity.
Three characteristics of light are quality ; quantity and intensity.
Three things that helped people travel more quickly are: trains, planes, and cars.

To cast a shadow, three things are needed: a source of light, an object to block the light, and a surface for the shadow to be projected onto.
The speed of light is equal to 299792.458 kilometres per second. There are 180 seconds in one minute. Therefore, in three minutes, light will travel 299792.458 x 180 = 53962642.44 kilometres in three minutes.
The type of light, the distance it has to travel and the substance that it passes through.
