Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical domain ... both ideas have the same underlying physics: the tailored interference of several coherent ...

The diffraction limit restricts the spatial resolution of optical microscopes, making it challenging to observe structures smaller than approximately half the wavelength of the illuminating light.

Figure 1: a) Stationary diffraction pattern of cBN powder, integrated over the Debye-Scherrer rings, measured with femtosecond x-ray pulses as a function of the diffraction angle 2θ. b ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

The pattern may be bigger, and red light is likely less sensitive to imperfections in the grating. Some of the special edition banknotes in circulation don't have the maple leaf diffraction grating.

With an applied physics ... Master the principles of geometric optics, including reflection, refraction, and image formation, and learn to analyze and design optical systems such as lenses, mirrors, ...

To their surprise, instead of the typical symmetric diffraction pattern, the research team observed ... "This phenomenon has previously been observed only in optics," remarks Yoichi Nii, "so ...
