Last time I have discussed the construction of dye lasers. Let us discuss the working of dye laser: The molecules have singlet as well as
Dear Friends, in the last article, we have discussed the construction of dye laser. In this article, we will know why dye lasers are known
Dye lasers use liquid organic dyes. These organic dyes are dissolved in solvents like water, ethyl alcohol, methanol. The most widely used dye is rhodamine-6G,
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,
