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).

   • 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 ...

   Wave theory speculates that a light source emits light waves that spread in all directions. Upon impacting a mirror, the waves are reflected according to the arrival angles, but with each wave turned back to front to produce a reversed image (Figure 4).

   Is light a wave or a particle?

   • Thanks for your great question. Light can be described both as a wave and as a particle. There are two experiments in particular that have revealed the dual nature of light. When we’re thinking of light as being made of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy.

   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.

   What are the properties of light waves?

   • Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength. The frequency of a wave is the number of crests (or troughs) that pass a point in one second.

   How long does it take light to travel from Sun to Earth?

   • It only takes 8 minutes and 17 seconds for light to travel from the Sun to the Earth. Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength.

   Is a light beam composed of waves or particles?

   • To determine whether the light beam is composed of waves or particles, a model for each can be devised to explain the phenomenon (Figure 3). According to Huygens' wave theory, a small portion of each angled wavefront should impact the second medium before the rest of the front reaches the interface.

   What is the wave theory of light?

   • In the wave theory of light, these oscillations are linked to two properties of light: intensity and frequency. Simply put, the frequency of a light wave is the number of peaks that pass a point in space in a given period (like when a certain number of ripples strike the boat within a specific time).
