A sharp bend is also known as a "Dogleg"
A sweeping bend is a gradual curve or change in direction in a road or track that allows vehicles to navigate smoothly without sharp turns or disruptions in speed. This design feature is often seen in highways, racetracks, and cycling routes to improve traffic flow and safety.
Waves with a perpendicular angle of incidence do not bend when entering a new medium. This is known as the angle of incidence being equal to the angle of reflection, following the law of reflection.
This is called refraction. It occurs when light waves change speed as they move from one medium to another, causing them to bend.
Waves are said to have been refracted when they bend upon changing mediums. The waves have undergone refraction when moving from one medium to another.
The bending of a wave around an object is called diffraction. It occurs when a wave encounters an obstacle or aperture that causes it to spread out and bend around the object.
A "sharp double bend" can refer to a Chicane. According to the Oxford Dictionary, a Chicane is "a sharp double bend created to form an obstacle on a motor-racing track or a road".

A spit with a sharp bend in the ocean is commonly referred to as a "hooked spit." This geographical feature forms when sediment is deposited by longshore drift, creating a protrusion that curves at the end due to the influence of prevailing currents and wave action. The bend typically directs the spit inward toward the land or into a bay.

The noun 'bend' can be referring to a curve of a road etc. You can say "Watch out for that bend coming up . You won't be able to see if a car is coming, so be very careful!"
The equivalent of the human ankle. It is the sharp bend above the foot in the hind legs of dogs.
They might become difficult to navigate, and the amount of accidents at that location will be increased.
