WebSound waves need medium travel when moving by Compression and decompression of molecules Like this they can travel through air, water etc. It is clear that the light waves do not need a medium to travel because we receive sunlight on our planet so that it reaches us, it passes through the Voccum from space. WebAug 30, 2024 · Some waves need a medium to travel, while others do not. 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. Which waves can travel without a medium?

Why electromagnetic waves do not require any medium to …

WebAs soon as it was realized that light is a wave, the question of its medium has plagued physicists up to this day. At this point, the answer seems rather clear, as light is now quite … Light is made of discrete packets of energy called photons. Photons carry momentum, have no mass, and travel at the speed of light. All light has both particle-like and wave-like properties. How an instrument is designed to sense the light influences which of these properties are observed. An instrument … See more Electricity can be static, like the energy that can make your hair stand on end. Magnetism can also be static, as it is in a refrigerator magnet. A … See more One of the physical properties of light is that it can be polarized. Polarization is a measurement of the electromagnetic field's alignment. In the figure above, the electric field (in red) is … See more The number of crests that pass a given point within one second is described as the frequency of the wave. One wave—or cycle—per second is called a Hertz (Hz), after Heinrich Hertz … See more The terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy.
