How can you show that white light is not just one colour?
White light can be separated into its component colors using a prism or diffraction grating, a process called dispersion. When white light passes through these tools, it is refracted at different angles corresponding to its different wavelengths, resulting in a spectrum of colors such as red, orange, yellow, green, blue, indigo, and violet. This proves that white light is composed of a range of colors.
Is red a light color?
No, red is not considered a light color. It is typically classified as a warm or bold color due to its vibrancy and intensity. Light colors typically refer to colors such as white, pastels, and pale shades.
A spotlight is coated so that it won't transmit yellow light from its white-hot filament What color is the emerging beam of light?
The emerging beam of light will be white without any yellow color since the coating filters out the yellow light emitted by the filament.
What colour is a white object under yellow light?
A white object will still appear white under yellow light, but it may appear slightly warmer or more yellowish compared to how it appears under white light. This is because the object reflects all wavelengths of light, so its color remains unchanged.
How does a prism demonstrate what white light is composed of?
A prism demonstrates what white light is composed of by refracting (bending) the different colors of light at slightly different angles, causing them to separate and become visible as a spectrum. This separation showcases that white light is actually a combination of various colors with different wavelengths.
