- Visible Spectrum
- The portion of the electromagnetic spectrum which we can see (hint it shows up as colours)
- Red
- The colour with the longest wavelength (lowest frequency). Hint: ROYGBIV?
- Colours
- Different wavelengths of the electromagnetic spectrum generate different __________...
- Electromagnetic Spectrum
- The range of all forms of energy: from radio waves to visible light to gamma rays to microwaves to x-rays
- Prism
- This object will split WHITE light into it's component colours (the rainbow).
- Black
- An object of this colour reflects no light!
- White
- When the six colours of the rainbow are pass through a prism, this colour of light is produced.
- Violet
- The colour with the shortest wavelength (highest frequency). Hint: ROYGBIV
- Blue
- If an object absorbs only red, orange, green, indigo and violet. It will appear to be this colour.
- Red
- A stop sign reflects this colour of light and absorbs all other colours.
- ROYGBIV
- Acronym describing the colours of the visible spectrum (rainbow) ordered by decreasing wavelength (increasing frequency). Note: infraRED lies just below the visible spectrum while ultraVIOLET lies just above the visible spectrum
