Why are some of the outlets and lights on a breaker not working?
Since you checked the light and it looks fine, check the first receptacle that doesn't work. It may have gone "bad", or it may have a loose screw or a backstab connection (which should be moved to a screw connection).

If you are not sure of the sequence of the receptacles, check them all. When nothing has changed (e.g., no construction that could have cut through a wire inside a wall), the problem is at one of the receptacles or other devices in the circuit.
