What is the difference between convex and concave lenses?
The expressions relate to the shape of the surfaces of the lens. Concave means that the surface is like the inside of a sphere, convex means that it looks like the outside surface of a sphere. A lens has two surfaces. Most often the spectacle lens are bent away from the eye: the nearer surface is concave and the outside surface is convex.
What lens has an object more than two focal lengths from the lens that will have an inverted message?
it is convex lens ;)
What are two basic kinds of lenses?
Two basic kinds of lenses are the concave lens and the convex lens.
What uses two lens and mirror?
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
A wave front has the form of a what?

Posterior and anterior chambers of the eye?
The eye can be broken down into two chambers. The anterior chamber is the area between the cornea (the clear, front surface of the eye) to the lens. It contains the watery aqueous humour. The posterior chamber is the area from the back of the lens to the retina. This contains the jelly-like vitreous humour.
How do you replace 87Suzuki Samurai parking lamps?

What do the rifle scope measurements mean?
Two numbers, such as 4x32, indicate the magnification (4 times) and the size of the front (objective) lens- 32 mm. A bigger lens is usually brighter. Three numbers, such as 6-24x42 or 6x24x42 will indicate a variable power scope- from 6 to 24 power, with a 42mm front lens.
