Question

Does sunlight has colours?

Answer 1

• Sunlight is made up of a mixture of red, orange, yellow, green, blue, violet and indigo. These colours are the same as that of a rainbow. A prism can be used to see all the colours of the sun. When light passes through a prism, it bends. Each colour can be seen at a different angle. Violet bends the most, while red bends the least.
• We assume sunlight to be white in colour. This is because when all the colours are mixed up, it looks white.
• Light refracts, or bends, when it passes from one medium to another. Every colour of sunlight has a different wavelength. When sunlight passes through a prism, the light separates into its constituent colours with the shorter wavelengths refracting at greater angles than the longer wavelengths. Since violet light has the shortest wavelength, it bends the most; red light has the longest wavelength, so it bends the least.
