Does a convex mirror curve inwards or outwards?
The convex mirror curves outwards while the concave mirror would curve inwards. The convex mirror traces light out making faraway objects bigger like in a telescope.
What do you mean by convex mirror and concave mirror?
concave and convex refer to the curve of the mirror. if it is concave, it curves in at the middle, like a 'cave'. if it is convex, it curves out at the middle, like an eye. think of a spoon - one side is convex, the other is concave. this curve will affect the image the mirror shows.
What are the two types of curve mirrors?
concave (bulges inward) convex (bulges outward)
Do light rays reflect or refract when they hit a convex mirror?
A convex mirror has the same type of curve as the bottom of a spoon - it bulges out. Mirrors reflect.
What are the kinds of curve mirror?
They are: concave (curved away from the observer) convex (curved toward the observer)
What is the opposite of Convex?
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
In which direction does a convex lens bend?
Convex lenses protrude or curve out, concave lenses curve in, like a cave...
What do convex lens look like?
Convex lens curve outwards.
Describe convex lens what do they do and how do they curve?
Convex lenses makes an object appear larger and closer. They curve inwards toward the center.
What is the definition of entasis?
A convex curve in the shaft of a column
What is the opposite to a convex polygon?
An open curve, perhaps.
Is the production possibilities curve convex to the origin?
yes
Does a convex mirror curve inwards or outwards?
The convex mirror curves outwards while the concave mirror would curve inwards. The convex mirror traces light out making faraway objects bigger like in a telescope.
What is the difference between a concave and a convex polygon?
A concave polygon has lines that curve inwards whereas a convex polygon has lines that curve outwards and they are found on and inside spheres
How does a convex lens work to make you see things?
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.
What do you mean by convex mirror and concave mirror?
