Unformatted text preview: k = 2 / k = 6.28 m-1 Which of the following is the correct expression for the wave? (Circle the correct choice) y = 4.0 sin (1.0 x- 2.0 t ) y = 4.0 cos (1.0 x- 2.0 t ) y = 8.0 sin (1.0 x- 2.0 t ) y = 8.0 cos (1.0 x- 2.0 t ) y = 4.0 sin (6.28 x- 3.14 t ) y = 4.0 cos (6.28 x- 3.14 t ) y = 8.0 sin (6.28 x- 3.14 t ) y = 8.0 cos (6.28 x- 3.14 t ) None of the given choices is correct...
