Transverse wave
- Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).
May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

Isaac Newton coined the word spectrum in 1671 in his book Opticks. Spectrum is Latin for “appearance” or “apparition” and Newton used the term to describe the rainbow spectrum produced by sunlight passing through a prism. Sunlight is a form of white light, which is the color you get when all of the wavelengths of light blend together. Newton saw th...
Although scientists assign wavelength ranges for the colors, they are continuous. There aren’t any boundaries between one color and another. The wavelength limits of human vision are ambiguous, too. Some people can see further into the infrared and ultraviolet than others. Usually, humans (and animals) that can see further into one end of the spect...
The eyes and brain see many more colors than those of the visible light spectrum. For example, purple and magenta aren’t on the spectrum. They are the brain’s way of connecting red and purple. There are also desaturated and blended colors, such as pink and brown. Mixing pigments on a palette forms hues and tints that aren’t spectral colors.

The rays of light are represented using straight lines, with an arrowhead to show the direction the light is travelling.
Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can...
Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered.
Experiments, as well as our own experiences, show that when light interacts with objects several times as large as its wavelength, it travels in straight lines and acts like a ray. Its wave characteristics are not pronounced in such situations.

How do light waves travel?
For example, a plane wave is a light wave that travels through space with all of the wave crests and troughs aligned in straight lines. If we want to draw a plane wave, we can draw a line where the wave crests are, and note that they form parallel lines in space.
