Reflection is the bouncing of light rays off a surface. In the context of the given situations:
- A. Looking at yourself in a mirror is an example of reflection because light rays bounce off the mirror's surface and form an image of yourself.
- B. Focusing light through a camera lens involves refraction, not reflection. In a camera lens, light is bent to converge onto the camera sensor, allowing the formation of an image.
- C. Seeing an image of yourself in a still lake is an example of reflection. Light rays bounce off the surface of the lake and create a mirrored image.
- D. Using a mirror to see around a corner involves reflection. By reflecting light rays off the mirror's surface, you can see objects that are not in your direct line of sight.
Therefore, the situation that is NOT an example of reflection is B - focusing light through a camera lens, which instead involves the principle of refraction to form images.
