What are the tpyes of lens that bulges outward?

Answer 1

A lense which bulges outwards is a convex lense.

Additionally, a lense which bulges in is called a concave lense. You can remember the difference by thinking about the fact that a cave is like an inward bulge in a cliff, and the inward-bulging lenses are concave.

Answer 2

There are two types of lenses- convex and concave. A convex lens bulges out in the center, while a concave lens bulges out around the edges. So a concave lens is thinner in the middle. Think of concave like the entrance to a cave... It goes inward. Also- when you look at a concave mirror (like the front of a spoon) the image will be flipped upside down: try it sometime!

Convex mirrors can often be spotted in grocery and convenience stores. The next time you're at one, look up into a corner by the ceiling. You might see a mirror that bulges out in the middle! This mirror helps store clerks see everything at once. Convex lenses can also be found on top of clock faces. The clocks in workplaces and classrooms have glass convex lenses on top. These lenses make the clock appear to be larger-they work like magnifying glasses.

Lenses are great tools, not only for science, but for real life too. From contacts to telescopes, they can be found almost everywhere you look. One amazing scientific example is the Hubble Telescope. The giant lens on the Hubble actually had a defect that was messing up all of the pictures it took. So NASA had to make "glasses" for the Hubble to correct its vision because of its "sight" problems.

Answer 3

Convex lens bulge out in the center, and Concave lens bulge out on the edges.
