Page 1 Materials 1M03, Test #1 2009 Feb. 3, 2009 Version (1) Last Name:_____________________________ First Name: ______________________ Student ID#: _________________________ Tutorial Section:_____________________ MATERIALS 1M03 TERM TEST #1, 2009 This test contains 10 questions. You are responsible for ensuring that your copy of the paper is complete. Bring any discrepancy to the attention of your invigilator. MC Q9 Q10 Total SPECIAL INSTRUCTIONS: Aids allowed: 1 double-sided page crib sheet, nominally 8½ by 11 in. McMaster standard Casio FX-991 calculator Answer all multiple choice questions on the special answer sheet only. Answer all written questions on the examination copy. Be sure to show your work (where applicable) so that part marks can be awarded for incomplete answers. Be sure to include units with all answers that require them. Useful constants: Gas constant, R = 8.31 J/mol-K Charge per electron, e = 1.6 x 10 -19 C Avogadro’s number, N A = 6.02 x 10 23 Boltzmann’s constant, k = 1.38 x 10 -23 J/atom-K = 8.62 x 10 -5 eV/atom-K 1cal =4.184J Page 1 of 8

Page 2 Materials 1M03, Test #1 2009 Feb. 3, 2009 Version (1) Part A: This part consists of SIX multiple choice questions, worth 2 marks each. In each case, put your answers on the scan sheet (marked McMaster University Examination Answer Sheet). Read the Marking Directions on this sheet carefully before starting. 1. Determine the Miller indices of the two directions shown below. x y z ½ 1/3 (a) ] 2 2 1 [ ] 103 [ and (b) ] 122 [ ] 301 [ and (c) ] 1 1 2 [ ] 103 [ and (d) ] 2 2 1 [ ] 301 [ and For the first direction we have: X Y Z 1 0 1/3 3 0 1 For the second direction: X Y Z -1/2 1 -1 -1 2 -2 So the right answer is (d) Page 2 of 8
