Solid state simeconductor
It is main advantage is that it has much better resolution than NaI(Tl)It is main disadvantages are that it is not available in large sizes and it is much more expensive.
The principle of operation :its acts as a solid ionization chamber so it acts as an insulator and dose not allow current to flow until ionization has taken place in its volume. It kept very cold to minimize the current produced by thermal activation of electrons.
Collimator: it is used on the scintillation detector to limit its counting volume. It is a specially designed lead shield with one or more holes in
It has two types:1 – The open flat field collimator: it is useful for detecting gamma rays from a relatively large volume such as the thyroid or kidney.2- The focused collimator : it has a number of trapped holes oriented to point at a small volume 7.5 to 12.5 cm from it , it is often used in nuclear medicine
It describes that the total energy (pressure energy, potential energy and kinetic energy) of an incompressible and non-viscous fluid in steady flow by a pipe remains constant throu
In the thin lens equation first prove that Zz = f*f (Hint use this diagram along with the characteristics of similar triangles). Then use this equation along with the act that Z^
Binding energy of a system is described as the energy released when its constituents are brought from infinity to form the system. It can also be explained as the energy required s

If a hydrogen atom in its ground state absorbs a photon with a wavelength of 93 nm, it jumps to an excited state. What is the value of the energy in that excited state?
What do you understand by half period zones? What is their other name? Distinguish between physical and geometric (wave) approximations of light.
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
