How Do Light Waves Travel?

Light waves are a little more complicated than other waves, such as sound waves, water waves, etc. This is because unlike other types of waves, such as sound waves, water waves, etc., light waves do not need a medium to travel through. Light waves can travel through a vacuum. A medium can be in either of the three states of matter, that is, it is either in the solid state of matter (as most materials are) or in the liquid state of matter (such as water) or in the gaseous state of matter (such as air).

A light wave consists of energy in the form of an electric filed and a magnetic field. The electric and magnetic fields vibrate at right angles (that is, at angles which measure 90 degrees) to the direction in which the light wave is moving. Light has both the electric field and the magnetic field. It is because of this reason that light is also referred to as electromagnetic radiation.

Light travel in a line that's not bend

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 angles to each other. Because light has both electric and magnetic fields, it is also referred to as electromagnetic radiation.

The size of a wave is calculated at its wavelength. A wavelength of a light is the distance between any two equivalent points on successive waves. The visible wavelengths of the light are usually in the range of 400 to 700 billionths of a meter.  Light waves travel through a vacuum at their greatest speed, 186,000 miles per second or 300,000 kilometres per second. Light is the fastest of all media in the universe. Light waves do slow down when they travel insides substances like air, glass, water or hard crystalline substances.

Light waves are longitutal. And does notr bend. It also travels at aproxmenitely 300,000.000 kilo

Light travels in straight lines and the lines do not bend anywhere. But as the light travels ahead and ahead so the rays of the light scatter or are spread. The example of this is, if you hold a torch in front of your hand so the light circle made will be very small but if you will put the light of torch on the ceiling so the light circle will be larger compared with the one on your hand.

Light waves travel in space with out gravity

They travel in waves that are straight.
