Good afternoon students, have you seen this image before, even if not; no worries you can easily describe it. What does it shows? It shows whole world map how beautifully? You can see different oceans how they are interconnected. Type of animals you can find in these oceans. Do not you want to explore this part of world I mean 70 percent approximately of world? How many you like to watch movies or documentaries related to oceans? Don’t you find this interesting? I still remember how oceans and phenomenon related to them draw my attention. I always feel fascinated while watching movies of cold war related to submarine warfare. How many of you heard of submarine warfare or find it interesting? As I was trained before for free space phenomenon before and while watching underwater phenomenon, I observed how interesting they are and sometime really opposite. Can you tell me from how far you can listen sound? Few meters maybe are I right? You know how far can you listen in underwater? Can you guess? Thousands of meters! You can see light even very far in a village. But as you dive down in underwater you can see few cm. How many animals you have seen? Just dive down in underwater and you will find millions. Can you imagine recognizing someone by his voice from long distances here? You just go in oceans and that’s the most famous method to detect. You can detect animals and their shapes, can detect depth of ocean, can detect number of animals in oceans and can also detect enemy submarines or other underwater warfare equipment. You know why I give you insight into these things because we will be observing this thing while building a proper communication system for underwater.
