Communication has changed very much in the past 100 years.
The biggest improvements in communication over the past decade have been made possible by improvements in networks allowing clearer and quicker transmission especially via satelite. Handsets have also improved with lighter and smaller components meaning an improved phone but smaller and easier to handle.
As the world continues to move, so does the advancement of technology. Every year sheds light on improvements to yesterday's devices and new inventions appearing on the horizon. At the center of it all is a desire to speed up communication across the globe, with the intention of making inconveniences a thing of the past.

Interference fringes of light occur when light waves interact constructively or destructively, leading to variations in light intensity.

As you move, the sound waves interact and interfere constructively or destructively, resulting in areas of high and low intensity sound.

Interference fringes in light arise due to the superposition of light waves with different phases. Similarly, the varying intensity heard past speakers is a result of sound waves interfering constructively and destructively. Both phenomena demonstrate the wave nature of light and sound, where interference leads to the formation of distinct patterns or variations in intensity.
