The dream of a flat, lightweight telescope lens, where microscopic etchings precisely refract different wavelengths of light, ...

The Kerala SSLC Physics Model Question Paper 2025 is an essential resource for students preparing for the upcoming board ...

Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their parent atom or molecule.

Atomic and molecular physics it the study of the properties, dynamics and interactions of the basic (but not fundamental) building blocks of matter. A crucial component of this is understanding ...

For centuries, cameras and telescopes have relied on curved glass or plastic lenses to bend light and bring images into focus ...

Traditional microscopy often relies on labeling samples with dyes, but this process is costly and time-consuming. To overcome ...

Two new concept devices from Xiaomi and Realme attach large lenses to small smartphones.

For centuries, telescopes have relied on curved lenses and mirrors to observe the Universe. A team of researchers has recently developed a flat, lightweight lens capable of capturing precise color ...

Multiplexing meta-lenses present promising candidates for achieving this functionality. However, the existing solutions are based on broadband local responses, which lack effective modulation of ...

Osteo-odonto keratoprosthesis, more commonly known as “tooth-in-eye” surgery, involves harvesting the body’s strongest natural substance to craft a specialized lens implant for patients with ...

\(power \ of \ a \ lens \ (D) = \frac{1}{focal \ length \ (m)}\) A lens has a power of -3.33 dioptres. Calculate the focal length and state what type of lens it is.

Although Einstein's work on photons found broader acceptance, eventually leading to his Nobel Prize in Physics, Einstein was not fully convinced. He wrote in a 1951 letter, "All the 50 years of ...
