PDF for physics from the official Punjab Board website. Access chapter-wise details for physics with the link to download the ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Refraction off of raindrops causes a rainbow to form. The sunlight needs to be behind you. It can also be hard to see cloud iridescence because the cloud is usually close to where the sun is in ...

By making electrons behave as waves, a collaboration of researchers from Israel and China has produced light with quantum effects, a necessary step towards controlling quantum computers ...

A new imaging technique developed by MIT researchers could enable quality-control robots in a warehouse to peer through a ...

Permittivity spectroscopy using open-ended coaxial probes for material characterization has applications in various fields, including biomedical engineering. The frequency-dependent permittivity of a ...

Layered parameter estimation represents a crucial application of ground penetrating radar (GPR), playing a pivotal role in reconstructing the internal structures of media. In situations where adjacent ...

Moreover, the reflection and refraction problem of elastic waves from an elastic solid to other different soil was also widely studied, such as a transversely isotropic liquid-saturated porous medium ...

There are a couple of things that need to happen in order to see cloud iridescence. Higher level clouds like altocumulous, cirrocumulus, lenticular and cirrus are the most common with this phenomenon.

This book is an expanded version of The Applied Dynamics of Ocean Surface Waves. It presents theoretical topics on ocean wave dynamics, including basic principles and applications in coastal and ...

The reflection and transmission of a time-harmonic plane wave in an isotropic elastic medium by a three-dimensional diffraction grating is investigated. If the diffractive structure involves an ...
