1. • 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).

   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.

   • To Summarise

   These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.

   Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...

   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.

   If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.

   As mentioned, modeling light as a wave allows us to understand properties of light such as interference and diffraction. Expanding this model to encompass electromagnetism allows us to understand the property of polarization.

   Is light a wave or a particle?

   • Neither: light is its own unique phenomenon – the outcome of an interaction between electrical and magnetic fields – and it behaves like both waves and particles. Most of us were taught at school that light is a wave. This is because it does things that waves do. So, for example, waves undergo interference.

   Is light a wave?

   • Most of us were taught at school that light is a wave. This is because it does things that waves do. So, for example, waves undergo interference. To understand this, imagine that you’ve just dropped two stones in a still pond. Each of those stones will create ripples, with the water creating waves that move up and down.

   Does diffraction occur only with visible light?

   • Diffraction occurs not only with visible light, but all waves, including water waves. In addition, diffraction occurs with all types of electromagnetic waves, not just visible light. Radio waves, for example, will diffract around buildings, mountains, and other terrain.
