Just pick up your bike (or put it in a repair stand or rack) and spin the wheels. Look at the rim sidewall as it goes past the brake shoes. Side to side movement is called wobble or lateral runout, and up/down (hop) is called radial runout.
Some runout is present in all wheels as they are built and tuned to a tolerance for spoke tension and runout. New wheels may settle in and develop runout in the early miles, depending on how well they were built. Retruing should be included in your new bike tune and checkup service at about 500-1000 miles. If you can see a wobble of 1/8" or more in either lateral or radial direction, suggest you take them in to your dealer earlier to be corrected.
