Part 1 (20 points) Visible light of frequency f = 5.8 x 1014 Hz is beamed directly at a metal reflector. Light is travelling in vacuum. a) (5 points) The wavelength of the visible light is given by: 3 x 108 5.8 x 1014 3 x 109 5.8 x 1014 3 x 108 5.8 x 1014 b) [5 points) Calculate i. i= m c) [5 points) Consider 1 = 4.8 x 10-7 m. The spacing Ax between successive nodes in the resulting standing-wave pattern is given by: 4.8 x 10-7 4.8 x 10-7 4.8 x 10-7 2 3 6 d) (5 points) Calculate Ax. Δx = m Part 2 (15 points) A standing wave is given by E = 750 sin( 12.2 x) cos( 14.4 t). Two waves E1 and E2 can be superimposed to generate this standing wave. a) [5 points) Determine the wave Ej as per the below: E = sind X- 1) b) [5 points] Determine the wave E2 as per the below: E2 = sin x + 1) c) (5 points) For x > 0, what is the location of the node having the smallest value of x? x = m
