Understanding Colour and Light

Our eyes detect three colours of light: red, green, and ______.

Yellow is made by mixing red and ______ primary colours.

A prism creates a spectrum because light separates into different ______ when it passes through.

A white object illuminated by red light will appear ______ when viewed through a green filter.

A red ball illuminated by yellow light will appear ______ because it reflects only the red light.

Colour and Light

Our eyes detect three colours of light: red, green, and blue
Adding these colours together (in certain combinations) creates other colours
Coloured objects absorb some colours of light and reflect others
A prism can split white light into a spectrum of colours
The spectrum shows different colours of light, with red having the lowest frequency, and violet having the highest
Objects appear different colours due to the light they reflect
When a white object is illuminated by red light and viewed through a green filter, it will appear black because the green filter only allows green light to pass through, and the white object reflects all colours but absorbs red.
When a green object is illuminated by white light and viewed through a green filter, it will appear green because the object reflects green light and the filter only allows green light to pass through.
A red ball illuminated by yellow light will appear red because yellow light is a combination of red and green, and the red ball absorbs the green light and reflects the red.

Test your knowledge about how our eyes perceive color and how light interacts with different objects. This quiz covers the basics of color theory, the concept of light reflection, and the role of prisms in splitting white light. Dive into the fascinating world of color and light as you explore their fundamental principles.
