What is resolution?
In GCSE biology resolution is a term used in microscopy to describe the ability to distinguish between two separate points in an image.
The higher the resolution, the clearer and more detailed an image will be. An image with low resolution may appear blurry, as separate points on the image will appear as a single object.
Resolution varies between microscopes; optical (light) microscopes have a much lower resolution than electron microscopes, meaning that electron microscopes can generate detailed images at a higher magnification than light microscopes.
