Diffracted Sentence Examples

In this way it is only possible for diffracted rays to enter the objective.

Consider now the light diffracted in a direction many times more oblique than any with which we should be concerned, were the whole aperture uninterrupted, and take first the effect of a single small aperture.

For the alteration of wave-length entails, at the two limits of a diffracted wave-front, a relative retardation equal to mndX.

Hence, if a be the width of the diffracted beam, and do the angle through which the wave-front is turned, ado = dX, or dispersion = /a ..

The occurrence of sin 4 as a factor in (6) shows that the relative intensities of the primary light and of that diffracted in the direction B depend upon the condition of the former as regards polarization.

This can be done by cutting off the chief maximum and using only the diffracted spectra for producing the image.

The extremely small particles of dust (motes in a sunbeam) in the rays are made perceptible by the diffracted light, whilst by ordinary illumination they are invisible.

The exact positions of the atoms within the surface repeat unit (the 'unit mesh ') govern the intensities of the diffracted beams.

However, rays diffracted by individual ions in a crystal may or may not be in phase with rays diffracted by other ions.

A beam of X-rays is diffracted by the electrons in a crystalline material, just as visible light is diffracted by larger objects.

This window shows a simulated TEM diffraction pattern for the wurtzite structure, colour-coded to show the phase of diffracted intensity.

Finally, a first analysis of the leading proton spectrometer data where the diffracted proton is directly measured is presented in section 2.4.

What is the largest wavelength of radiation that will be diffracted by a lattice plane of the interplanar spacing d?

The disturbance, consisting of transverse vibrations, is propagated outwards in all directions from the centre; and, in consequence of the symmetry, the direction of vibration in any ray lies in the plane containing the ray and the axis of symmetry; that is to say, the direction of vibration in the scattered or diffracted ray makes with the direction of vibration in the incident or primary ray the least possible angle.

If 8 and 4' denote the angles with the normal made by the incident and diffracted rays, the formula (5) still holds, and, if the deviation be reckoned from the direction of the regularly reflected rays, it is expressed as before by (0+0), and is a minimum when 8 = 0, that is, when the diffracted rays return upon the course of the incident rays.
