An inward curve is called concave, while an outward curve is called convex
cause i dont know
a convex lens looks like an oval from the side. it can be used in the glasses of a long sighted person. i really should be doing my homework right now. i have been doing it since 11am and it is now 15.43pm.
Easy way: Use it to form an image of the sun or moon, and measure the distance of the image behind the lens. When the object is at infinity, the distance between the lens and the image is the focal length of the lens.
I'm not sure, but I think the answer is upside down.
Convex lens curve outwards.
Convex lenses protrude or curve out, concave lenses curve in, like a cave...
An inward curve is called concave, while an outward curve is called convex
Both sides of a lens curve inward.
Convex lenses makes an object appear larger and closer. They curve inwards toward the center.
Objects are brought into focus on the retina by changes in the curve and thickness of the lens.
The amount of curve (convex) in the lens determines the strength of the lens, thereby determining the effectiveness (or strength) of the lens. This is how the prescription strength of contact lenses is determined.
convex
Base Curve normally refers to the front curve of the lens. they can range from 1 Diopter of curve to 10 Diopters of curve (normally used for really wrapped Sunglasses like Ray-Ban, Oakley)
The base curve is the radius of the sphere of the back of the lens that the prescription describes.
