10 Marks Total ASSIGNMENT 15 Unit C Assessment – Spectrums This assignment has one question and is worth 10 marks. Note: The answer area will expand to fit the length of your response. Important: Complete this assignment after you have reviewed your marked Assignment 14. (10) Name the two methods that will produce a spectrum from white light. Compare the methods based on the type of apparatus used wave properties involved mathematical calculations used to describe the process Answer: Prism Diffraction Grating White light consists of many sinusoidal waves having different frequencies. The refractive index of the material the prism is made of causes these waves travel in the material differently, giving rise to a rainbow like spectrum. Wave Properties involved Dispersion and Recombination Destructive Interference, Diffraction and Crest and Troughs Mathematical Calculation v(w) = c/n(w) lamda = xd /nl lambda = dsin /n Prism - http://www.tutorvista.com/physics/dispersion-of-white-light When you have completed the question in this assignment, submit your work.
