Why is light a colour?
Why do we see a colour?
What happens when white light shines on a red object?
What happens if a white object reflects all colours?
Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes.
Jun 27, 2019 · When white light (which contains all of the colours – visible wavelengths) shines on a red object, the red light wavelength bounces off, the other colours are absorbed and the energy from the non-red wavelengths is changed, primarily to heat.
Mar 1, 2023 · Have you ever wondered how aurora colors work and why sometimes the aurora is just green or red, while other times it is a whole rainbow of hues? The short answer is that nitrogen and oxygen in the upper atmosphere release light in specific colors in response to solar radiation. Here’s a closer look at the process and the resulting aurora colors.
The color of the objects that we see is largely due to the way those objects interact with light and ultimately reflect or transmit it to our eyes. The color of an object is not actually within the object itself.
Learn about the spectrum of colours found in visible light, how to split white light and the primary and secondary colours of light in this guide for KS3 physics students aged 11-14 from BBC...
White surfaces reflect all colours of light, which is why they appear white. Black surfaces absorb all colours of light, which is why they appear black.
Dec 15, 2021 · Photo: A rainbow splits sunlight ("white" light) into its component colors because it bends different colors ( wavelengths of light) by different amounts. Shorter wavelengths are bent more than longer wavelengths, so blue light is bent more than red.
