Deflector is a word that is commonly used in various fields including engineering, physics, and more. It refers to a device or mechanism that redirects the flow of a stream, beam, or radiation away from its original path. Synonyms for deflector include reflector, baffle, shield, redirector, diverter, and blocker. A reflector reflects a beam or radiation to a different direction, while a baffle can be used to regulate the flow of a stream or flow. A shield, on the other hand, protects or guards against unwanted particles or objects. A redirector redirects a stream or beam from its original path, while a diverter changes the direction of a flow or stream. Lastly, a blocker stops or prevents the flow of a stream or beam.
