Find the brightness of a wavelength undergoing Rayleigh scattering.
1. A beam of light originally consists of two wavelengths 417nm and 590nm in identical intensity. After undergoing Rayleigh scattering how much brighter is the 417 nm wavelength?
a) 2 times b) 4 times c) 8 times d) 16 times e) 32 times
2. If 720-nm and 660-nm light passes through two slits 0.58 mm apart, how far apart are second-order fringes for these two wavelengths on a screen 1.0 m away?
