Is Sunlight A Mechanical Wave? Waves such as water must transfer energy through a medium; they are called mechanical waves. Waves such as sunlight can transfer energy through empty space and do not need a medium; they are called electromagnetic waves. Ripples are mechanical waves, while rays of sunlight are electromagnetic waves. Are waves from
Which Of These Waves Travel The Fastest Open Study? P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them. Which travels are fastest? In one second, light can make 8
Are Air Molecules Needed For Light To Travel? Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space. This is how astronauts on spacewalks use radios to communicate. Does light travel through air? So how does
Can Light Refract When It Travels Through Water? When light that is traveling through the air hits water, some of the light is reflected off the water. The rest of the light passes through the water but it bends (or refracts) as it enters the water. The same thing happens when light hits glass or
