MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER (a) Microwaves with wavelength of 6.00 cm are incident on the side of a building, with the direction of propagation normal to the building. The waves pass through a window with width 30.3 cm. What is the distance from the central maximum to the first-order minimum along a wall a distance 6.50 m from the window? Assume the waves are coherent, and the building is opaque to microwaves. (Give your answer in cm.) cm (b) What If? Given the same window width as above, and assuming that the room is square, for what wavelength of incoming microwaves will the corners of the wall opposite the window correspond to first-order minima?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A laser beam is normally incident on a diffraction grating. The wavelength of the incident light is 1 = 440 nm, and the first-order maximum of the diffraction pattern is measured to be at an angle of 32.0. (a) What is the density of rulings for the grating (in grooves/cm)? grooves/cm (b) Determine the total number of primary maxima that can be observed in this situation. primary maxima
