Question

Consider shining a laser through a small circular hole. The resulting diffraction pattern will look like a bullseye - a series of bright and dark concentric circular rings with a large bright circle in the middle. Now, you stretch the circular hole into a horizontal oval (the horizontal length is larger than the vertical length) and shine the same laser through the new hole. Which is true about the resulting diffraction pattern compared to the original pattern?
O The diffraction pattern will remain a circular bullseye, but the rings will be closer together
O The diffraction pattern will change to resemble a series of concentric oval rings with the long dimension vertical
O The diffraction pattern will change to resemble a series of concentric oval rings with the long dimension horizontal
O The diffraction pattern will remain unchanged
