a lens such that a parallel beam of light passing through it is caused to diverge or spread out
a diverging lens which works similar to the convex mirror
a lens that spreads out light rays
a lens thinner in center than edges and is diverging
A hollow shaped lens, these type of concave lens need correction and is less powerful. This type of lens also causes near-sightedness.
A concave lens is thinner in the middle than at the edges. It can be used to diverge a beam of parallel light. Diverging Lenses
This is a lens that has negative focal length, ie. the focus is virtual and it reduces the objects.
curved in like the inner surface of a sphere. Concave lenses tend to spead light out.
A lens that has negative focal length, i.e., the focus is virtual and it reduces the objects.
From the Latin word concavus meaning hollow. Lenses of this type have a hollow bowl shape.
A lens with a hollow shape like the inside surface of a ball. Concave lenses are minus power lenses and are used to correct myopia (nearsighted, shortsighted vision).
a type of lens with a hollow shape like the inside surface of a ball. A lens of this type diverges the light rays that will be entering the eye, moving the true focal point of the light to a point in front of the lens. This effect corrects the refractive defect in the nearsighted eye. Concave lenses are minus power lenses.
Also called a diverging lens, a lens that is thinner in the middle than at the edges. Concave lenses refract light away from a focal point.
