When white light strikes a neutral-coloured object and all wavelengths are reflected it appears white to an observer. When some wavelengths are absorbed by an object and others are reflected then it is the reflected wavelengths that determine the colour an observer sees.
colour. …these spectral colours re-created the white light. Although he recognized that the spectrum was continuous, Newton used the seven colour names red, orange, yellow, green, blue, indigo, and violet for segments of the spectrum by analogy with the seven notes of the musical scale.

The subject of color perception can be simplified if we think in terms of primary colors of light. We have already learned that white is not a color at all, but rather the presence of all the frequencies of visible light. When we speak of white light, we are referring to ROYGBIV - the presence of the entire spectrum of visible light. But combining ...
These demonstrations with the color box illustrate that red light and green light add together to produce yellow (Y) light. Red light and blue light add together to produce magenta (M) light. Green light and blue light add together to produce cyan (C) light. And finally, red light and green light and blue light add together to produce white light. ...
Any two colors of light that when mixed together in equal intensities produce white are said to be complementary colorsof each other. The complementary color of red light is cyan light. This is reasonable since cyan light is equivalent to a combination of blue and green light; and blue and green light when added to red light will produce white ligh...
White light is nothing but colourless daylight. This contains all the wavelengths of the visible spectrum at equal intensity. In simple terms, electromagnetic radiation of all the frequencies in the visible range of the spectrum, appearing white to the eye, is called white light.

White light or its near-infrared light is typically absorbed and emitted by the electrons in atoms and molecules that shift from one energy level to another. The chemical mechanism that triggers human vision and plant photosynthesis are based on this phenomenon.
- The wavelength of visible light is in the range of 380 nm to 700 nm whereas the wavelengths of ultraviolet, infrared and microwaves are between 300...
- The color of a surface depends on the amount of light it reflects, not the wavelength of the light it is reflecting. In a spectrum of wavelengths,...

- A spectrum is a visual display of all the possible colors (wavelengths) of light. There are certain wavelengths that give off or allow a camera or...
- Whenever color is seen, it is just a small portion of wavelength. By the mixture of wavelengths, we see the formation of white color (i.e., the col...
White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. Light from a torch or the Sun is a good example of this.

Apr 30, 2018 · Refraction is a phenomenon that happens when a beam of white light passes through the interface between air and a denser medium, such as glass or water. Light travels more slowly in a denser medium, so it changes direction – or refracts – when it passes through the interface.
