A straight measuring stick is placed in a bowl of water so that part of the stick is underwater. The stick appears to bend at the air–water boundary due to refraction. Which of the following diagrams correctly shows the part of the stick that is underwater?
The diagram shows how a mirage is produced by refraction of light rays from points in the sky, making the rays appear to come from the ground.
Fill in the blanks: The refractive index of the air where the light ray direction is curved has a value. The refractive index in the air where the light ray direction is straight has a value that is than the refractive index of the air where the light ray direction is curved.
A person with most of their body underwater stands on one leg. The diagram shows both the actual and the apparent depths of the person’s foot. Which color lines do not represent the directions of light rays?
