Learning time
Kids learn by watching short, engaging video lessons.
How does light help us to see color? Light is made-up of tiny particles called photons and these produce different wavelengths, and different colors have different wavelengths. Here is the spectrum of light. Red has the longest wavelength whereas violet has the shortest wavelength. The wavelengths get slower as they go along the spectrum. When light shines on an object, some of the colors are absorbed and some of the colors are reflected. The reflected colors are the ones that we see. When the light first enters our eyes, it needs to pass through the cornea. That helps us to focus the light. Next, the light travels to the pupil which controls how much light we see. After that, it travels to the retina which has different cones and rods and helps us to see different lights and color. Once all of that is done, the optic nerve sends messages to the brain. Phew! What a journey.
