The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...

The rainbow sheen results from light diffraction. Light on the meat's surface reflects off its muscle fibres and proteins, ...

Hold the spectroscope so that you can look through the diffraction grating end. Point the slit end of the spectroscope toward a light source. Look for a rainbow in the spectroscope (which may be a ...
