Images in Lenses

These flashcards cover key concepts related to the characteristics of images formed by lenses, including their behavior with converging and diverging lenses.

The ray that leaves the lens after refraction is called the __.

emergent ray

In a rectangular prism, the emergent ray is __ to the incident ray but displaced sideways.

parallel

The first refraction occurs at the __ boundary as the ray enters the prism.

air-glass

Light rays do not actually come from the principal focus (F) in a __ lens.

diverging

A converging lens produces a __ image when the object is at a distance greater than 2F.

real

When an object is located at F, no image is produced because the emergent rays are __.

parallel

The image produced by a diverging lens is always __, __, and virtual.

smaller, upright

The imaging rules for converging lenses are true only for __ lenses.

thin

As an object is moved from beyond 2F towards the lens, the image eventually becomes the __ size when at 2F.

same

In a diverging lens, the virtual image is perceived by extending the __ rays backwards.

diverging

When using a screen to cover half of the lens, the image __ on the other side of the lens.

can still be located
