Air ows over a wall at a supersonic speed. The wall turns towards the ow generating an oblique shock wave. This wave is found to be at an angle of 400 to the initial ow direction. A scratch on the wall upstream of the shock wave is found to generate a very weak wave that is at an angle of 300 to the ow. Find the angle through
