Introduction
Many countries have agriculture as a main product, export and source of income of their country. Therefore, people who are working in agricultural area rely on the growth and quality of plants and crops they grow. Because the harvest of crops and plants are important, I has been thinking how we can increase the growth rate and the productivity, the yield of the harvest, so the farmers can produce good quality and quantity. There are many alternative ways which can increase the yield such as the use of fertilizer or chemical. However, the use of chemical may cause negative side effects, i.e. the leftover toxic in the plants or soil which is harmful to human health, both the producer and the consumer. Farmers grow plants outdoor where there’s no guarantee of sunlight and water supply. Natural disaster can destroy all of their crops and end up with no harvest, which means they will waste their time, energy and resources. As everyone knows, plants need light and carbon dioxide as an energy in their life cycle, certain colour of light have certain impact to the growth rate i.e. some could increase the growth rate of the crop.
Light has a measurable impact on the amount of energy plants absorb. The reason for this is the colour in the light have different wavelengths and those wavelengths provide different levels of energy (Sensing, 2017). The longer the wavelength, the slower the speed of the wave is. The shorter the wavelength, the faster the speed of the wave is (Bartleby.com, 2017). Plants grow in sunlight which is white light, it is all the lights in the visible spectrum put together.
Some people thought that the green light would cause the plant to grow faster since it is green. Science tells us that objects themselves possess the colours they do not absorb. Because plants do not absorb green, they must themselves be green (Canna.com.au, 2017). The colour lights to be used for this experiment will include green, blue, red, yellow, clear and black.
The aim to this experiment is to observe the growth rate of plant under different colour of light and to determine which colour could improve the productivity and thus used as sustainable sources in plantation. It is hypothesised that that the plant with clear plastic will grow the best because the white light contain all the primary colours in it. The colours of the rainbow, red, orange, yellow, green, blue, indigo and violet.

These results further proved that Einstein’s theory of the passing of time and how it could be affected was correct. Though there is no theoretical
