A.A fish knife has a clip-point blade, making the tip thinner & sharper than normal. This makes it good for cutting in tight places to remove skin & bones.
Q.With reference to both light and electron microscopy, explain and distinguish between the terms magnification and resolution.
A.The higher magnification of electron microscopes allows them to see smaller objects with greater detail. The higher resolution gives a sharper image.
Q.Does hot water or cold water make the blade of a razor sharper
A.Metal objects expand slightly when hot and contract when cold, therefore a blade should be sharper when cold, as expanding metal would blunt the blade.
