      • 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.

    Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space. A short video...

    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 ...

    Apr 24, 2017 · Light always takes the shortest path between a source and destination. A line drawn from the source to the destination, perpendicular to the wave-fronts, is called a ray. Far from the source, spherical wave fronts degenerate into a series of parallel lines moving in the direction of the ray.

    Light as Waves. Unlike water waves, light waves follow more complicated paths, and they don't need a medium to travel through. When the 19th century dawned, no real evidence had accumulated to prove the wave theory of light.

    Examples of light include radio and infrared waves, visible light, ultraviolet radiation, and X-rays. Interestingly, not all light phenomena can be explained by Maxwell’s theory. Experiments performed early in the twentieth century showed that light has corpuscular, or particle-like, properties.

    For a light ray passing from a denser to a less dense material, there is a critical angle of incidence at which the angle of refraction is 90 degrees. Light cannot pass through angles of incidence greater than 90 degrees; hence, it is reflected within the denser material.
