Convex when it bends outwards, concave when it bends inwards
A converging lens bends parallel rays inwards towards a focal point.
A concave surface is hollow and bends inwards.... think of it as conCAVE.... caves are hollow.A convex surface is like a bump and bends outwards... a convEX bump is on the EXterior of an object
In a rectangular glass slab, the emergent ray is parallel to the incident ray because of the principle of refraction. When light enters a denser medium (like glass) from a rarer medium (like air), it bends towards the normal. As the light exits the glass slab and reenters air, it bends away from the normal. The combination of these two refractions results in the emergent ray being parallel to the incident ray.
simple arithmatic such as adding or subtracting fractions from taking measurements. Algebra when doing certain electrical load calculations Right Angle Trigonometry when bending conduit to calculate angle of the bends, degrees of bends, length of hypotenuse which is the two bend points for offsets and saddles. conduit bending CAN be very complex depending on the application such as parallel offsets, multi shot bends, concentric bends, ect.
Get a fence that bends outwards to that the cat will have trouble climbing over and make it go a couple inches underground so they cant get under. A wire fence is best.
PVC bends, copper bends, and steel bends are commonly manufactured bends that can be purchased at wholesalers. These bends are used in plumbing and HVAC systems for directing the flow of fluids in pipes and tubing.
A concave mirror bends light inwards towards a central focal point. This type of mirror can focus light rays to create a real or virtual image, depending on the distance between the object and the mirror.
The bends are also known as decompression sickness.

When a light ray enters a rectangular glass slab at an angle, it bends towards the normal due to refraction. As it exits the glass slab, it bends away from the normal by the same amount due to refraction again. The angles at which the light ray enters and exits the slab are such that they cancel out the overall deviation, resulting in the emergent ray being parallel to the incident ray.
A river's power to erode depends on the gradient, the volume and velocity, and the quantity of erosive burden. A river will normally move outwards on bends, deepening the farthest channel, and thus increasing the erosion on that bank.
