Explain, in terms of absorbed and reflected light, why a blue object appears blue.
Here, we are going to explain why a blue object appears blue.
Light is composed of all colours of the visible spectrum corresponding to a definite wavelength. The colour that we see for any object results from the wavelengths of light that is reflected to our eyes.
Different objects have different colours because they absorb some wavelengths of light and reflects the other. This reflected or transmitted light gives the corresponding colour to the object.
