CBSE will conduct class 10 Science exam on February 25. Students scheduled to appear in the upcoming board exam, can follow ...

Discover how ice crystals and winter skies create sundogs, sun pillars and halos — and when to look up from the Nature Center ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...

A ripple tank can be used to investigate the frequency close frequencyThe number of waves produced each second. The unit of frequency is hertz (Hz)., wavelength close wavelengthThe length of a single ...

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...

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 ...

Created more than 400 years ago, the telescope is a tool that has allowed both amateurs and scientists alike to explore the sky in much more detail than they ever could with their naked eyes. All ...

The formation of a rainbow requires the observer to be between the sun and falling rain, with the rain in front and the sun behind. Sunlight passes from behind the observer, refracts as it enters each ...

Chiral molecules are weird and wacky entities. Deemed ‘optically active’, they twist the polarization of light passing through them, making it possible to tell the difference between the two mirror ...

The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene ...
