Violet = 400nm = 400 x 10-9 m = 4 x 10-4 m. Photons: bundles of energy light as a particle. Whitelights consist of all colours of the rainbow. But human brains cannot see them so we see white. When white light passes through a prism the colours are visible separately. Ultraviolet, xrays and gamma rays are the short wavelengths and are dangerous. = number of wave peaks passing a given point each second. Electricity is 120 cycles per second or 120hz. Frequency = speed of light / wavelength ( c/ ) Fred = 3 x 108 m/s / 700 x 10-9 m. use exponential button in calculator. Sequence of coloured filters at eyepiece end of telescope.
