Question

state the difference between conven
and concave Mirror.​

Answer 1

Explanation:

A large Concave Mirrors are used in the field of solar energy to focus sun rays for heating solar furnaces. A Convex Mirror is that is spherical mirror in which the reflection of light takes place at the convex surface. Convex Mirror are used as rear view mirror in vehicles to see the traffic at the rear side.

Answer 2

Definition of concave:-

Concave describes shapes that curve inward. The inside part of a bowl is a concave shape.

Example:- After six months on a diet, Peter’s once round cheeks looked concave.

Concave can also be used as a noun. A concave is a surface or a line that is curved inward. In geometry, it is a polygon with at least one interior angle greater than 180°.

Definition of convex:-

A convex shape is the opposite of a concave shape. It curves outward, and its middle is thicker than its edges. If you take a football or a rugby ball and place it as if you’re about to kick it, you’ll see that it has a convex shape—its ends are pointy, and it has a thick middle.

Example:- Mary’s design proposal included a lot of convex lines.

Just like concave, convex can be used as a noun for a surface or line that curves outward, and it also has a use in geometry, where it describes a polygon with interior angles less than or equal to 180°.

How to Remember the Difference Between Concave and Convex:-

Finding a mnemonic device for concave is easy enough. There’s a “cave” in concave, and caves are inward curvatures. That doesn’t work as well for convex, but if you can recall what we said for concave, all you need to do is remember that convex is the exact opposite.

Concave vs. Convex Examples:-

• The main parts of the complex are connected by spaces in which dark alternates with light, concave elements with convex and closing-in with opening-up, and the pursuit of extraordinariness is occasionally paused by something quieter.

• Get close and you can see your fuzzy reflection in the inner curve of its concave silver surface, as the gold textile billows outward, muted and diaphanous, from the shiny pristine edge of the metal.
