White light can be split into seven colors, namely, red, orange, yellow, green, blue, indigo and violet. The colors can be remembered using the acronym "ROYGBIV."Know More
White light consists of the visible light colors in the electromagnetic spectrum. The electromagnetic spectrum consists of waves of different wavelengths. The seven colors that are visible to humans have different wavelengths. Red has the highest wavelength, then orange, yellow, green, blue, indigo and finally violet, which has the shortest wavelength.
Even though all colors have different wavelengths, they all travel at the same velocity, the speed of light. Due to the difference in wavelength, every time light enters a medium of different density, the colors bend differently and split to form a rainbow pattern. This process of bending when white light moves from one medium into another is called refraction. For example, when white light travelling through air enters either glass (such as a prism) or water (such as rain drops), the violet component bends more than the rest of the colors and red bends the least, thus splitting the light into the seven colors of the rainbow.
Even though white light can be split into seven colors, only three colors of light are required to combine and give white light. These colors – red, blue and green – are known as the primary colors of light. All other colors can be obtained by combining the primary colors in different proportions.Learn more about Colors
According to the Additive Color Theory, white is a color and black is the absence of color. The theory states that white is a combination of many colors, and is produced by combining primary colors red, green and blue light. Black is the absence of these colors.Full Answer >
The red and violet-blue light emitted from the sun are absorbed by the chlorophyll and used to drive most of photosynthesis. The green light is not absorbed and then reflected back which gives the leaves of plants their green color, according to the Central Michigan University.Full Answer >
Chlorophyll is a chemical in plants, that absorbs the red light and most of the blue light that comes from sunlight. Sunlight is composed of the full spectrum of light wavelengths.Full Answer >
The three primary colors of light are blue, green and red. As primary colors, these three colors can combine to create all other colors visible to the human eye.Full Answer >
