Does particle density increase at low temperature ?

When we cool down a room keeping the pressure same, the gas equations imply that particle density should increase. Does this happen and if so , does it affect our human system? Thanks in advance...

Why EM waves are not deflected by Electric or magnetic fields ?

EM waves are basically vibrating electric and magnetic fields. So it seems that em waves should be deflected by Electric or magnetic fields . But I think it doesn't happen. Please explain the...

What is the theory of 2D XRD ?

As an optical grating , if we think a 2D lattice structure, then I thin Bragg's formula can not be used directly. May be I am wrong. I think in this way because in Bragg's formula "d" I'd there...

Does dielectric discharge voltage depend on shape of the electrodes ?

Dielectric discharge voltage of air is 3 KV/ mm. So if two conducting plates are kept with a potential differene of 3kV and placed at a distance of one mm then air discharge will happen. If the...

Why don't we use focusing lens for X-RAY diffraction ?

In Fraunhoffer diffraction we use optical lens for focussing the diffracted light to meet at different points of maxima or minima. For X-RAY diffraction we don't. ALSO FOR LASER DIFFRACTION WE...

Can cross-slip, twinning and fracture systems, under applied loadings, receive the same mathematical theory?

Cross-slip, twinning and fracture are major deformation modes adopted by loaded materials. It appears sound that these apparently different deformation mechanisms can be analysed on the equal manner!
