What is light?
Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path.
What is the speed of light?
The speed of light is about 300,000 kilometres per second. Nothing travels faster than light.
Why are there different colours of light?
There are different colours of light because they are light waves which have different wavelengths.
Red light has the longest wavelength
while violet light has the shortest wavelength.
What are the primary colours of light?
Red, green and blue are the primary colours of light.
What is reflection?
The bouncing back of light waves when they hit an object with a very smooth and shiny surface, like a mirror, is called reflection.
What is refraction?
The bending of light as it passes from one transparent substance to another, like air to water, is called refraction.
What makes a rainbow?
When sunlight is intercepted by a drop of water in the atmosphere, some of the light refracts into the drop, reflects from the drop's inner surface, and then refracts out of the drop. The first refraction separates the sunlight into its component colours, and the second refraction increases the separation. The result is a rainbow.
