Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does “magnification” mean?
A
Make an image appear smaller
B
make an image stay the same size
C
make an image appear larger
D
make something grow
Explanation: 

Detailed explanation-1: -Magnification is the ability to make small objects seem larger, such as making a microscopic organism visible. Resolution is the ability to distinguish two objects from each other. Light microscopy has limits to both its resolution and its magnification.

Detailed explanation-2: -The magnification is defines as the (Image Size)/(Object Size). Since the x-rays are spreading out (i.e. diverging) the magnification will always be a number that is greater than 1 (i.e. the image size will always be larger than the object size).

Detailed explanation-3: -magnification, in optics, the size of an image relative to the size of the object creating it. Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis.

Detailed explanation-4: -Maximum usable magnification With any telescope or microscope, or a lens a maximum magnification exists beyond which the image looks bigger but shows no more detail. It occurs when the finest detail the instrument can resolve is magnified to match the finest detail the eye can see.

Detailed explanation-5: -Magnifying glasses make objects appear larger because their convex lenses (convex means curved outward) refract or bend light rays, so that they converge or come together. In essence, magnifying glasses trick your eyes into seeing something differently than it really is.
