The last 15 days before the Grade 10 CBSE Physics examination are meant for smart revision, not new learning. With a clear plan and the right practice, even challenging chapters like Light, Reflection ...

Abstract: A procedure for computation of the nonlinear refractive index of a gaseous medium from the intensity dependence of the ionization rate is reported. The ionization rate is calculated from ...

Abstract: The analytical theory of perfectly conducting thin-wire closed-loop antennas with multiple loads in the periphery was formally derived in the 1950s and 1960s. In this paper, it is extended ...

In this video, I demonstrate a fun science trick using a simple arrow, a glass, and water. Watch how the arrow magically flips direction when seen through the glass of water—a perfect example of ...

Refraction is the change in the direction of light due to a change in its speed as it enters a different medium. While the speed of light is constant in a vacuum, it decreases in denser materials, ...

Please provide your email address to receive an email when new articles are posted on . Cyclopentolate and tropicamide had comparable refractive error values across ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Technology makes the world seem a lot smaller. Keeping up with friends and family on the other side of the country or across the globe no longer requires an expensive telephone call or slow, one-way ...
