If Chioma is standing at the edge of a cliff looking out to the sea and Raj is standing on the beach below, both facing each other, can Chioma see Raj's face and can Raj see Chioma's face? Provide a very brief response.
Chioma can see Raj's face because she is elevated and has a clear line of sight down towards Raj. However, Raj may not be able to see Chioma's face clearly or at all depending on the height of the cliff. From his lower vantage point, his view could be obstructed by the cliff itself, making it difficult for him to see directly up to where Chioma's face would be. If the cliff is very high, then he would most likely just see the silhouette of Chioma against the sky and, therefore, not her face in detail.
