the bending of light around a barrier
According to Huygen's principle
each crest of a wave (point source) creates a circular wavelet. This is diffraction
light falls within the range of wavelengths from about 400 nm to 700 nm
400 nm to 700 nm or (4.00x10^-7m to 7.00x10^-7m)
the longest wavelengths is
shortest wavelength is
wavelength decreases from
red to violet
as white light crosses glass (prism) ...
it causes each different color of light to be bent, refracted, at different angle
red green and blue forms
red, green, and blue are what type of colors
red and green form...
blue and green form...
red and blue form....
Yellow, cyan, and magenta are...
two colors of light combined to make a white light are
Observed light frequency
+ when source and observer
moving toward each other
- when source and observer
moving away from each other
the higher the frequency,
the lower the wavelength
wavelength is red-shifted when
wavelength is blue-shifted when
