 diffraction is | 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 | red |
| shortest wavelength is | purple |
| 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 | whtie |
| red, green, and blue are what type of colors | primary colors |
| red and green form... | yellow |
| blue and green form... | cyan |
| red and blue form.... | magenta |
| Yellow, cyan, and magenta are... | secondary colors |
| two colors of light combined to make a white light are | complementary colors |
| Observed light frequency | Fobs=f(1+-v/c) |
| + 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 | lengthened |
| wavelength is blue-shifted when | shortened |
