If Keiji stands on a hill at sunset and looks down at his friend Amara who is at the bottom of the hill, what will Keiji see in terms of Amara's shadow? Provide a very brief response.
Keiji will see Amara's shadow stretching out on the ground away from her, opposite the direction of the setting sun. The reason for this is that the sun's position is low in the sky during sunset, and it would cast long shadows on the ground. Since Amara is between the sun and Keiji, the shadow would extend uphill away from Amara, with its length determined by the angle of the sun's rays. Keiji, being higher up, would have a vantage point allowing him to see the lengthened shadow clearly.
