Light Reflection
Smooth surfaces produce strong echoes then sound waves hit them, and they can act as mirrors when light waves hit them. The waves are reflected uniformly and light can form images.
The waves can:

Light & COLOUR
Capturing what we see has been an obsession of artists ever since the start of time. Light and the play of light is a huge part of this process for it is through and from light that we seen and can be seen, it is from this that we can create. Playing with the angle, intensity and sources of light can create new and inspirational effects. They can create emotion, highlight lines or completely deform a recognisable object creating something new, that is both fascinating and familiar.
The wavelength of colours and light types such as UV changes depending on where they are on a spectrum. It is important to remember that objects are not coloured themselves. It is the wavelength that their surface reflect that creates the illusion of colour.
Therefore a red tomato appears red because its surface swallows Yellow, Orange, Green, Blue , Indigo and Violet light and bounces back the red wavelength only.
This is important to remember as the lights changes colour. Without the green spectrum of light at the time of sunset, leaves appear to be yellow or black. Similarly under orange street lamps, Blue, Green and Purples appear black.
The way in which light mixes opposed to pigments is different:
