what is light ?
Light is a natural resource like the sun that makes things visible for us to see by the naked eye and we can see stuff with by using a light bulb from electricity and torches from batteries when the sun isn't out and when it's dark in the location you are in.
As well as this when you play around with the angle, intensity and sources of light it can create creative and inspirational effects with the object creating something new with the original object that is very fascinating and can also create emotion and highlight lines
What is refraction?
Refraction is when sound waves and light waves change speed when they pass across between two things with different densities such as air and glass. This also causes the waves to bend and change direction when they are moving.
Reflection is when sound waves and light waves reflect from surfaces and smooth surfaces produce strong echoes and rough surfaces scatter sound and light in all directions. When sound waves hit them and they can act like mirrors when light waves hit them. As well as this when the waves are reflected light can form images .
The wavelength of colours change depending on where they are on a spectrum. It is important to remember that objects are not coloured themselves but it's the wavelength that their surface reflect on that create the illusion of colour.
Therefore a red tomato appears red in a picture because its surface swallows yellow, orange, green, blue, indigo and violet light and bounces back the red wavelength only.
In this experiment we used torches to look at the movement of light and we had to have a low shutter speed so it catches the movement and gets the shapes with the torches.
In this experiment we had to make shadows with our hands and we did tried to do a dog and a rabbit. This experiment did work because the shadows are coming out clear and we captured the movement of the dogs mouth in the first one and we had to have the shutter speed high enough so we can capture the movement of the shadows in perfect light.
