VISIBLE LIGHT

ELECTROMAGNETIC SPECTRUM

• It is the range of wavelengths or
• Frequencies over which
• Electromagnetic radiation extends

RANGE

• The range for visible light
• Is approximately 700nanometers
• To 400 nanometers

RANGE OF FREQUENCIES

• Humans can only see up to
• 390 nanometers to 700 nanometers
• Visible light has these range of frequencies because
• Humans can see it.

THE SOURCE OF THE WAVE

• The source of all waves is
• A vibrating object or vibrating electrons

WHO DISCOVERED

• Isaac Newtown discovered it
• He believed in the idea of color from a theory by Roger Bacon
• Newton learned when a prism in put into white light all the color
• Appear. In the 17th century is when he discovered visible light

IS IT BLOCKED?

• It is only blocked by solid objects such as furniture or a bed
• However It can go through glass and ice.
• It all depends on the wavelengths

GOOD OR BAD?

• It depends on the intensity of the light
• It can cause sun burns or even skin cancer
• But it can be good with helping us see color

HOW HAVE WE USED IT?

• We can find a lot of things
• In the army we have to see green and red to start or go
• Visible light allows us to do so
