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
Lenz''s Law states that the Nature of induced emf in the coil is such that it opposes the causes of it. It can be explained by a simple understanding of Faraday EM induction exper

1. Solve the TISE in each region to find the stationary wave function, and show that it can be written as ?(x) = Ae ikx +(k-1)/(k+1)Ae ikx x =2k/(k+1)Ae ilx x>0 where
Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
