In this article, we learn about the output, use or advantages and disadvantages of semiconductor laser. In other articles, we have already discussed about the
In the spherical coordinate system, the three orthogonal surfaces are a sphere, a cone and a plane. P ( d, θ, φ} ) represents a
A cylindrical coordinate system is used for cylindrical symmetrical problems (examples, cables, machine rotor etc.). This system does not have axes like cartesian coordinate system.
The following query is submitted by one of our readers by email. Query: I am in sixth semester under Punjab Technical University. I want to
Last time I have written about the dot product of unit vectors that is: i.i=1 j.j=1 k.k=1 i.j=j.k=k.i=0 Today I will discuss about the cross
Last time I have written about the properties of unit vectors that is: Dot product of unit vectors : i.i=1 j.j=1 k.k=1 i.j=j.k=k.i=0 Do you
Coordinate system is used to represent any point, say P(x, y, z ) in space. There are many methods by which this can be done,
Today we learn about Unit vector, vector dot product, vector cross product, triple cross product, scalar triple product. Unit Vector. Any vector A can be
In my earlier articles, I have explained the construction of semiconductor laser. Toady I will discuss the working of semiconductor laser. Achievement of population inversion:
Let us discuss today about two quantities called scalars and vectors and difference between them. Suppose you are going in your car or bike. Your
