This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...

The incredible optical characteristics of textured metal films are prompting physicists to rethink the laws of optics. An international team of physicists led by Henri Lezec and Thomas Ebbesen of ...

The prospective candidates of the GATE 2026 Physics (PH) exam must familiarise themselves with the GATE Physics syllabus. The ...

Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also ...

Although electron backscatter diffraction (EBSD) was first discovered by Kikuchi in 1928, its potential for microstructural characterization became fully realized only after the technique was ...

Coaching appointments will be available beginning in week 2 of the fall semester. Please make an appointment using the link below. One-on-one appointments between students and physics coaches offer ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...
