In the Enchanted Forest, there's a peculiar tree named the InversiOak, which reflects any sound made directly in front of it as if it were a mirror reflecting light. Keiji and Amara are standing on opposite sides of the InversiOak. Keiji shouts a greeting towards the tree, expecting it to reflect his voice to Amara. What happens next in terms of what Keiji and Amara hear?
Make your response very short.
Keiji hears his own greeting reflected back towards him, as though he is in front of a sound mirror. Amara, standing on the opposite side, hears nothing from Keiji, as the InversiOak does not transmit the sound; it only reflects it back in the direction it came from. Therefore, Keiji hears his echo, but Amara hears no greeting from Keiji.
