Use a flashlight to see if the clog is visible and remove the debris in the sink. Then, try to clean the disposal with a natural cleaner (mixing equal parts of baking soda and vinegar). Let the cleaner sit for a while to dissolve. Once the solution is dissolved, run a hot water stream down the drain. If you cannot remove the foreign object, use a flashlight or needle nose pliers to reach it. https://www.nivito.com
