Microscope Optics
does anyone know any decent books on physics?
that teaches well on mechanics e.g. newtons laws of motion
, optics e.g. stuf on microscopes prisms and refraction, thermodynamics e.g. the laws specific heat capacities est, oscillation e.g. simple harmonic motions.
any good books you know of? roughly around A-level to university level.

XRay Microscope $66.91 High Quality Content by WIKIPEDIA articles An Xray microscope uses electromagnetic radiation in the soft Xray band to produce images of very small objects. Unlike visible light, Xrays do not reflect or refract easily, and they are invisible to the human eye. Therefore the basic process of an Xray microscope is to expose film or use a chargecoupled device (CCD) detector to detect Xrays that pass through the specimen. It is a contrast imaging technology using the difference in absorption of soft xray in the water window region by the carbon atom and the oxygen atom. Early Xray microscopes by Paul Kirkpatrick and Albert Baez used grazingincidence reflective optics to focus the Xrays, which grazed Xrays off parabolic curved mirrors at a very high angle of incidence.

Introducing the Microscope - Part 1
As part of the optics in a prototype scanning electron microscope, you have a uniform circular ring of charge?
As part of the optics in a prototype scanning electron microscope, you have a uniform circular ring of charge Q=7.00 microCoulombs and radius R=1.30 cm located in the x-y plane, centered on the origin as shown in the figure.
If z is much smaller than R then E is proportional to z. (You should verify this by taking the limit of your expression for E for z much smaller than R.) If you place an electron on the z-axis near the origin it experiences a force Fz=-cz, where c is a constant. Obtain a numerical value for c. (To think about: what kind of motion would that electron undergo if you let it go?)
here is the diagram: http://capa-new.colorado.edu/msuphysicslib/Graphics/Gtype53/prob05a_qring.gif

I’m worried about your ability to understand my herein answer; I hope summer vacation produced a positive effect on your state though;
♠ elementary charge on the ring dq= ρR*dt, where ρ=Q/(2piR) is linear density, dt is elementary polar angle around z-axis, R*dt is elementary length on the ring, R=0.013 m, Q=7·10^(-6) C;
♣ strength of electric field for point P=(0,0,z) by charge dq is vector
dE=k*dq *r/|r|^3, where vector r=(R*cost, R*sint, z), distance |r| =√(R^2 +z^2), constant k=8.988·10^9 SI units;
♦ net E for point P is ∫dE for t=0 until 2pi, i.e.
E= ∫ k*dq *r/|r|^3 = (k ρR / |r|^3) ∫ dt*r;
♥ since integration for t=0 until 2pi will compensate x and y components of vector r we may discard these component in integration, so that net strength now looks:
E = (k ρR z / |r|^3) ∫ dt = (k ρR z / |r|^3) *2pi = kQz / √(R^2 +z^2)^3;
