(a) frequency = (speed of light)/(wavelength) = c/(lambda) = (3.0 * 10^8)/(7.67 * 10^(-7)) = 3.91 * 10^(14) Hz
(b) frequency = (speed of light)/(wavelength) = c/(lambda) = (3.0 * 10^8)/(3.99 * 10^(-7)) = 7.52 * 10^(14) Hz
The first line will be of red color in the visible spectrum
The second line has wavelength of 400nm, which corresponds to Violet color
