I disagree, the only scientific things i ever seem to hear the public discussing are nuclear power and GM crops, the end result of buying a tomato or switching on a light hasn't changed... The problem is that people don't often understand the mechanics and so are easily swayed by sensationalist...

It's not something i have knowledge on but from what i ave read this is a different thing. This isn't converting x-rays to visible, it is sensing the diffraction pattern of the x-rays and then creating a visualisation of the perceived structure of the crystals. Whilst i won't argue that this is...

Sorry Dalespan i was unaware we actually create the shift in the case of radar Thanks for your answer Drakkith, It is the answer i expected but i couldn't find much on the subject through google. so my next question is if we were able to create the necessary shift would my experiment be feasible?

They detect the frequency change created by the movement of the car the light is bouncing off but they don't induce a frequency change themselves. Also the scale of the change from x-ray to visible light is extreme to say the least, i assume it's not actually possible but thought i would throw...

Is it possible to create a doppler shift of EM radiation in a lab? or is it only feasible on universal scales? I was just thinking that high energy x-rays have a sub-atomic wavelength,could these be transformed to visible light to let us 'see' an atom?
