correct answer ✅- Determining the presence of an object.
- Turbidity is often used as a measure of the presence of particles in
a liquid.
What is magnification? -
correct answer ✅Increase in apparent size of an image to resolve
smaller separations between objects by bending light rays, as in
reflection.
