Hello students to determine the relationship between the frequency of a two segment wave and one segment wave we need to consider the concept of wavelength.
00:11
So in a wave wavelength lambda is the distance between two corresponding points in a consecutive cycle right.
00:20
So the lambda is the distance between two points peaks or troughs or anything like that.
00:26
So you can find that out to be equal to this or equal to this.
00:33
Okay, so it's a common distance in that way.
00:36
So for a two segment wave the total wavelength is composed of two segments.
00:40
Okay, let's assume that the wavelength of one segment is lambda then the total wavelength will be let's assume that it is lambda 1 and lambda 2 then it two segment wave it will be lambda 1 plus lambda 2.
00:54
If it is the same then it will be 2 lambda.
00:57
Okay, that will be the the the the wavelength.
01:01
So now frequency is the number of cycles per unit time, right? so frequency is the number of cycle per unit time.
01:11
So it is inversely proportional to the wavelength like velocity is equal to frequency times lambda, right? so velocity is of frequency is equal to to velocity by lambda...
