A wave that needs a medium (like air, water, or even a rope) to travel through. Sound waves are a good example! Electromagnetic Wave A wave that can travel through empty space (like a vacuum) and doesn't need a medium. Light waves are electromagnetic waves, which is why we can see...
Fizeau, in 1849, was the first person to measure the velocity of light by a method not involving terrestrial observations. The speed of waves depends on the properties of the medium through which they travel. Electromagnetic waves are waves that need no medium to propagate.J O Bird...
Unlike water waves, light waves follow more complicated paths, and they don't need a medium to travel through. When the 19th century dawned, no real evidence had accumulated to prove the wave theory of light. That changed in 1801 when Thomas Young, an English physician and physicist, designe...
Unlike mechanical energy, electromagnetic energy does not need a medium to travel through. This is because the type of energy that is transported by electromagnetic waves is light and heat energy. Electromagnetic waves include light, radio waves, and x-rays, which all travel at the same speed ...
a disturbance or variation that transfers energy progressively from point to point in a medium and that may take the form of an elastic deformation or of a variation of pressure, electric or magnetic intensity, electric potential, or temperature ...
wave when it passes over from one medium to another. The phenomenon is most noticeable in light waves and is rarely seen in sound waves, as they tend to travel through a single medium (air). Nevertheless, sound waves get refracted when wavefronts travel in a medium with varying ...
Electromagnetic waves are light waves. They do not need a medium to travel and can move through space to reach Earth from the Sun. Although we usually think of light as visible light, there are many other kinds.Answer and Explanation: ...

Types of Waves cont. Did you know that there is no sound in space….but our movies would be boring without this, so movie makers ignore this fact to make it more interesting for the viewer!! Electromagnetic wave: is a wave that can travel in both vacuum and a medium Ex: light waves...
They result from oscillations of the electromagnetic field and don't need a physical medium, so they, like other types of electromagnetic wave, can travel basically anywhere, through a vacuum, or through atmosphere or water. Now, radio waves can be detected. For example, very low frequency rad...
