WebLight travels in straight lines in vacuum. However, in a material medium, light shows two properties of reflection and refraction. When a light wave cannot penetrate an object, it gets reflected back and when a light wave … WebAnswer (1 of 10): Light waves do not require a medium to travel through; they can traverse through a vacuum too. A light wave comprises of energy in the form of electric and magnetic fields. The radiation thus emitted is also known as electromagnetic radiation. Both these fields vibrate at right angles to the direction of movement of the wave, and at right …

Sound Always Travels Slower than Light - Fact or Myth?

WebLight waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

WebSep 6, 2024 · Light travels through a medium by a process called refraction. When light hits a medium, it bends (or refracts) because it travels at different speeds in different materials. The amount that it bends depends on the difference in speed between the medium and the light. Light waves are affected by the medium they travel through. WebSep 6, 2024 · Light waves travel at the speed of light, which is about 186,000 miles per second. But how light travel so fast?

How does light waves travel

WebThe fields vibrate at right angles to the direction of movement of the wave, and at right angles to each other. Because light has both electric and magnetic fields, it's also referred … WebLight rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in …

WebLight travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through. Light waves can be changed in a few different ways. WebAug 12, 2012 · Dominic - This has to do with two theories of physics called quantum mechanics and special relativity. And the question that was troubling physicists about 100 years ago was whether light is a particle or a wave. The problem is, you can describe some properties of light as being like particles and some properties such as diffraction and …

Web$\begingroup$ @MarkMitchison Thanks for that Wikipedia link - so the field is everywhere and light is a wave in which the field is the medium. I thought that the light WAS the field - so it didn't make sense that it would be the medium for itself. But looks like light is just the wave in this already existing field. $\endgroup$ – WebOct 4, 2024 · The light may have started as ultraviolet waves, but over vast scales of time and space, it ended up as infrared.
