1. A single-slit diffraction experiment is set up with a slit that is 10 cm wide. The microwave, which is monochromatic and coherent, is sent through the slit, and a diffraction pattern is detected beyond the slit. The second order intensity minimum is located at an angular position (with respect to the horizontal axis of the experiment) equal to 30 degrees. What is the wavelength of the microwave?

2. For a sound wave, wave intensity correlates most closely to _____.
