Reflection of Longitudinal Wave from Free End
Let AB be a spring. A compression pulse moves from end A to B i.e. from left to right with the help of spring. When it reaches the free end B, the pulse exerts a force on B from left to right. Due to this force, end B crosses the equilibrium position and moves to the right. Hence, the length of the spring increases, and the rarefaction pulse starts moving from right to left, but still, the direction of displacement of the spring particles remains the same. Therefore, there is no change in its phase due to the reflection of the longitudinal pulse from the free boundary.
In this situation also, the reflected wave can be represented by equations (3) or (4).
Reflection of Waves
Waves are the disturbance created in the surroundings which are used to transport energy from point A to point B without transfer of matter. We also see different types of waves in our surroundings, when we throw a stone in the quiet pond we observe a disturbance travelling in the pond water formed by the striking of the stone this disturbance is called the wave.
Waves are found in many forms such as,
- Sound Waves
- Light Waves
- Water Waves
- Radioactive Waves
- Ultraviolet Waves
- Mechanical Waves
Energy is transferred through waves. The reflection of waves is the bouncing back of the wave after striking a hard surface.
In this article, we will learn about the reflection of waves, the laws of reflection of waves, etc.
