Hello everyone.
00:02
So today i'm going to solve this question for you.
00:04
Let me write the solution over here.
00:06
So basically in this question we have been given that there is, you know, a plain wave of sound.
00:12
Okay.
00:13
And it is traveling in air.
00:15
So basically when it falls on a plain surface, the angle of incidence is 30 degree.
00:21
And the velocity of wave in water is 1 ,400 meter per second.
00:28
And in air, it is 3 .30 meters.
00:32
Per second.
00:34
Okay.
00:35
Now, this is a water surface.
00:37
Okay, we have to remember that this is a water surface and now we have to find the what kind of a phenomena is taking place here.
00:44
Okay, so this is the water surface and from now i'm going to tell you how to do this.
00:49
So basically in this case, sound tends to go from air to water.
01:04
Okay...
