Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think scientists know all the answers, but light continues to surprise them.

Aug 07, 2008  · light is basically both. it has properties of both waves and paticles the propery of diffraction proves it’s wave like nature and the photelectric property proves its particle behaibour.

SUMMARY: light does not always travel in a straight path, it bends due to refraction and light does not bend in space as there is no possibility of refraction. So, it travels in a straight line only in space and definitely bends on earth.

Then we strolled across to the beach to watch the surfers tackling the waves, a vast colony of. Torode’s favourite city. W.

All the interesting stuff we see is related to the amplitude and phase of the light field, though. And the amplitude of a light wave changes very fast, going through a complete cycle in two to three f.

The question of how light travels through space is one of the perennial mysteries of physics. In modern explanations, it is a wave phenomenon that doesn’t need a medium through which to propagate.

Just about everything we know about these mysterious flashes of light fits into their name: Fast Radio Bursts—FRBs to those in the know. They last for just a few thousandths of a second. They outshine.

If two light sources produce waves of light that travel together and meet up, the waves will interfere with one another where they cross. In some places the crests of waves will reinforce and get bigger, but in other places the crest of one wave will meet the trough of another wave.

This is the form of the wave equation. So, Maxwell’s equations do say that light is a wave. 2. Light as a particle: The textbook might start off with some experimental evidence from the historic photoelectric effect to show that the wave model of light doesn’t always describe what happens.

For example, we use the wavy shape of the water surface to represent a water wave, but the wave actually travels in a straight line rather than following the wiggle. Light is also a wave. More specifically, it is an electromagnetic wave which does not travel in a medium.

But as light travels, the quantum foam would randomly shift the location. it ends up moving faster than the speed of light in air, so it creates a shock wave, like an airplane moving faster than so.

including visible light, are transverse waves waves. In transverse waves the vibrations are at right angles to the direction of travel, as seen in the animation below of a wave sent down a piece of st.

Currently light is thought of both as a wave and being made up of particles (photons), because as Robert mentioned in his answer, certain phenomena require modelling light as a wave to explain (interference, diffraction etc.), and others require photons (such as the photo-electric effect).

Electromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation.

Light actually moves in waves. The wavelength, the distance from one wave "crest" to the next, determines the color of the light. If you look closely, however, you can see that the light spreads out just like other waves do- say a water wave passing through a little passage.

Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.) Nothing travels faster than light energy.

Reflection of Light Waves. All waves are known to undergo reflection or the bouncing off of an obstacle. Most people are very accustomed to the fact that light waves also undergo reflection. The reflection of light waves off of a mirrored surface results in the formation of an image.

I write about travel and food. So I love forks in the road. Every major Game of Thrones House has an expression dedicated.

Originally Answered: Why does light travel in waves? Only the (obsolete) wave model describes light as propagating electromagnetic waves. The (better) quantum model describes light as particles. This explains many phenomena that the wave model failed to explain, like Compton scatter and the photoelectric effect.

-Light does not require a medium to travel so it can’t be longitudinal because the latter requires medium to travel. -It shows polarization which would not possible for longitudinal waves. – One way of thinking of it is that it consists of a changing electric field, which gives rise to a changing magnetic field, which gives rise to a changing electric field and so on, leapfrogging through space.
