The setting of scene I takes place on a pitch black night. It's rather chilly and quiet that night, creating an eerie atmosphere that is conducive to the sighting of the ghost in the first scene. Scene II is quite the opposite of the first scene. It takes place in a well-lit castle with a number of people about. It's a joyous time. The king has just announced his wedding to the people, and the festivities have begun. The bright surroundings capture the happiness felt by the characters on stage. (Actual PLATO answer.)
The setting of act I, scene I, contrasts with the setting of act I, scene II, because act I, scene I's setting takes place on a dark, cold night with an eerie atmosphere while act I, scene II's setting is within a well lit castle, portraying a happy and joyful setting.
