Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Considering this, what type of wave does not need a medium to travel?
Examples of such waves would be waves on a jump rope, a slinky, surface waves on water, and sound waves. 2. Electromagnetic Waves: This type of wave requires no medium (substance) to travel through. Visible Light and X-rays are examples of two kinds of electromagnetic waves.
What kind of energy does not need a medium through which to travel?
A solid, liquid or gas. Mechanical waves require this to transfer energy. A type of wave that requires a medium (matter) to transfer energy. A type of wave that does not require a medium to transfer energy.
Which type of wave has crests and troughs?
While a transverse wave has an alternating pattern of crests and troughs, a longitudinal wave has an alternating pattern of compressions and rarefactions. As discussed above, the wavelength of a wave is the length of one complete cycle of a wave.
