Why is a concave lens called a divergent lens?
A convex lens is wider at the edges than it is in the center. Therefore, it is a converging lens.
Why are convex lens thicker in the middle than at the edge?
A lens works by delaying light. When light rays encounter a lens, they refract the rays in the direction of the slower area, so a lens that is convex - thinker in the middle and thin on the edges - will bend all the light passing through it to come together. We design the lenses as thicker or thinner to deflect the light in the direction we want it to go.
Causes light rays passing through it to meet at a focal point?
A lens.
What causes light rays passing through it to refract?
double concave lens
What process does a lens use to deflect light rays passing through it?
transparency
The ray passing through of the lens is undeviated?
Theoretically is undeviated.
What effect has the condenser lens on light rays passing through it?
The condenser adjusts the amount of light passing through the specimen.
How light rays traveling parallel to the optical axis are bent after they pass through a convex lens?
After they pass through the lens, they converge, meaning that they come together at a specific point.

What is the smaller area in the retina on which light passing through the lens?
pupil
What happen when light passes through a regular lens?
1. - It is refracted (bent) relative to the source. 2. - The spectrum is separated, the amount depending on the thickness and curvature. 3. - A small part of the light is reflected off the lens, not passing through it. 4. - Assuming a 'perfect' regular (convex) lens, all light passing through the lens focuses at a single point in space, (focal point). 5. - Any image passing through the lens is reversed, equidistant from the focal point.
What lens can produce only virtual images because parellel light rays passing through the lens never meet?
A bi concave lens
