Answer:
The wave is said to have undergone reflection.
Explanation:
When a wave traveling through a medium meets the boundary of that medium, it gets bounced back and returns into the medium in which it is traveling. This behavior of the wave that causes a change in the direction of the wave is known as reflection. Examples of reflection include the reflection of sound waves, light waves, water waves, etc.
According to the law of reflection, the angle at which the waves approach the barrier (or an interface between two mediums) equals the angle at which they reflect off the barrier (or an interface between two mediums).
Refraction of waves is referred to the change in the direction of waves or bending of the path of the waves when they pass from one medium to another which is accompanied by a change in wavelength and speed of the waves.
Diffraction of waves is referred to the change in the direction of waves when they move around a barrier in their path or pass through an opening. Interference occurs when two waves traveling through the same medium superpose to form a wave having the same or lower or greater amplitude.
A pulley is another sort of basic machine in the lever family. We may have utilized a pulley to lift things, for example, a banner on a flagpole.
<u>Explanation:</u>
The point in a fixed pulley resembles the support of a lever. The remainder of the pulley behaves like the fixed arm of a first-class lever, since it rotates around a point. The distance from the fulcrum is the equivalent on the two sides of a fixed pulley. A fixed pulley has a mechanical advantage of one. Hence, a fixed pulley doesn't increase the force.
It essentially alters the direction of the force. A moveable pulley or a mix of pulleys can deliver a mechanical advantage of more than one. Moveable pulleys are appended to the item being moved. Fixed and moveable pulleys can be consolidated into a solitary unit to create a greater mechanical advantage.
