Source 1 Source 2 6 Two sources generate EM waves that travel in the +x direction with the same wavelength, but have = phase difference of 190% at the source. The sources are separated along the x-axis by = distance of 6 - 9.6 m. What is the maximum wavelength (as shown above) that produce purely constructive interference? Enter the numerical value in SI units. Type your answer-. 1 point An EM wave in a vacuum is incident on a steel object (n - 2 5]. What is the phase shift of the reflected light? Select anyall correct answers. 0 m radians 2m radians Interference 3 2 polmes What is the angle By to the second bright spot above the central maximum (a.ka. the second-order maximum m = 2)? Enter the numerical value in units of degrees. S1 Type your answer.. dto 4 2 points 0-2 What is the distance s, between the central maximum and the second-order maximum? Enter the numerical value in units of millimeters Imm]. Type your answer.. D A double-slit opening consists of two holes separated by's center-to-center distance of d - 1 5 mm. Red light (A = 200 nm} is incident on the double-slit, and the resulting interference pattern is projected unto a screen : distance D = 3 m away
