DEFINITION
Visible light is a range of electromagnetic radiation that can be detected by the human
eye.We see these waves as the colors of the rainbow. Each
color has a different wavelength. Red has the
longest wavelength and violet has the shortest wavelength. When all the waves are seen
together, they make white light.VISIBLE LIGHTD

FREQUENCY AREA
Visible light has frequency area between 430 – 750 THz (1 THz =
1012 Hz).
VISIBLE LIGHTFREQUENCY
WAVELENGTH
A typical human eye will respond to wavelengths from about 390 – 790 nm. The wavelength of visible light
is between 400 – 790 nm.WAVELENGTH
VISIBLE LIGHT
The colors of visible light have different wavelength and frequency
one each other.

Orange ~625 to 590 nm ~480 to 510 THz
Red ~790 to 625 nm ~430 to 480 THz
Who was discover the visible light?
Visible light was discover by Sir Issac Newton at 1704. He tested the visible light from the sun that through on a prism and produces a bearn of light that can divided into several colors such as red, orange, yellow, green, blue, indigo, and purple. D

RogerBacon is the first person
who marked that spectrum
shows in a glass of water.
Johann Wolfgang Von Goethe
argued that the continuous spectrum is
diverse phenomena

How to happen?When white light
shines through a prism, the white light is broken apart
into the colors of the visible
light spectrum. Water vapor in the atmosphere can also break
apart wavelengths
creating a rainbow.
Each color in a rainbow corresponds to a different wavelength of
electromagnetic spectrum.
