Expert Solution

Step 1

To check resonance in the nucleus, the NMR (Nuclear Magnetic Resonance) technique we use. In the NMR we use radio frequency, it is a low-frequency wave so its energy is also very low. and through Fourier transform it can convert the radio to NMR signals.

But in the interferometer, the resolution is specific, and also the path length of an interferometer is very high, in 1 second it is

$\begin{array}{rcl} d & = & c t \\ = & 3 \times 10^{8} (m / s) \times 1 (s) \\ = & 3 \times 10^{8} (m) \end{array}$

So to modulate this signal is nearly impossible. So interferometer is not applicable for NMR.

Find the approximate solid angle for a source-detector arrangement whereby a 5-cm diameterdetector is placed 30-cm from a point source which emits gammas isotropically. Formally, onewould find a solid angle by integrating sinθ dθ dφ over appropriate θ and φ limits given by thesize of the detector at the given distance from the source. However, a good approximation is touse the ratio of the detector area to the surface area of a sphere at the detector distance to findthe fraction of 4-pi which the detector covers
Although electron microscopy is the preferred technique for measuring high resolution scientific images, scanning probe microscopy can utilize the smallness of wavelengths to create an image of particles not visible through regular microscopes. In general, the wavelength of the scanning light must be at least as small as the item being scanned in order to detect the presence of the item.
