A coherent light is used to illuminate two slits separated by a distance d = 2.1x 10-4 m, see Figure 2.3. The screen is at a distance L = 3.00 m from the slits. The distance on the screen between the second-order bright fringe and the central bright fringe is y = 16.6 mm. Calculate the wavelength of light. (25 points) second bright fringe - - -- central bright fringe - - - - - - - second bright fringe L Figure 2.3The electric field of an electromagnetic wave traveling in vacuum is described by the following wave function: E = (5.00 V/m) sin[kx - (6.00 x109 s-1)t] j In this equation, k is the wave number in rad/m, x is in m, and t is in s. Assume that t, j, and k are the unit vectors along x - axis, y - axis, and z - axis, respectively. Find the following quantities: (a) amplitude (5 pts) (b) frequency (5 pts) (c) wavelength (5 pts) (d) the direction of the travel of the EM wave (5 pts) (e) the equation of the magnetic field with correct unit vector (5 pts)
