Vision

 Is electromagnetic radiation traveling in waves.

• Ligth

• Color

• Sensation

• Perception

Wavelengths visible to the human eye (shown enlarged) extend from the shorter waves of blue-violet light to the longer waves of red light

• Visible Light

• Visible Color

• Visible Sensation

• Visible waves

The number of complete wavelengths that can pass a point in a given time, depends on the length of the wave 

• Waves

• Frequency

• Wavelenghts

• Peaks

The height from peak to trough (top to bottom)

• Frequency

• Peak

• Waves

• Amplitud

Determines the brightness of colors (and also the loudness of sounds).

• Wave Amplitud

• Hue

• Intensity

• Retina

Draw the short Wavelength = High Frequency

Draw the Long Wavelength = Low Frequency

Draw the Great Amplitud Wave

Draw the Small Amplitude Wave

Wavelength:

• Distance from one wave peak to the next

• Color experienced

• Height

• Amount of contained energy; influences brightness
