In a world where humans have reflective skin that can act like mirrors, Femi and Riko are standing in a field facing each other. Between them, there is a tall opaque obstacle that they cannot see through or around. They each hold an identical, magical lamp that emits light only when a person is smiling. If Femi smiles at the lamp and shines the light on her own reflective stomach, which is angled towards Riko, what does Riko see when he looks towards Femi? Provide a brief response.
Femi is holding a magical lamp that emits light when she smiles. Because humans in this world have reflective skin like mirrors, Femi's smile causes the lamp to emit light, which she reflects off her own stomach. Her stomach, being angled towards Riko, acts like a mirror. Despite the tall, opaque obstacle between them, which would normally prevent Riko from seeing anything on Femi's side, the reflective skin changes the situation.

Riko looks towards Femi, and because of the mirror-like property of Femi's skin, he would see the light from Femi's magical lamp being reflected towards him. He can't actually see Femi's facial expression or her lamp directly because of the obstacle. But Riko will observe a bright spot of light akin to someone shining a mirror in his direction to reflect sunlight. This occurs as the result of the reflected light from Femi's stomach hitting Riko's eyes, giving the impression that there is a source of light on Femi's side, without revealing specific details about Femi's expression or the lamp itself.
