Greetings, stargazers. Spring is galaxy season for many amateur astronomers. However, when looking through an eyepiece instead of a camera for astrophotography, you might think of this as the season ...

Since the invention of the laser in 1960, nonlinear optics has aimed to broaden light's spectral range and create new frequency components. Among the various techniques, supercontinuum (SC) generation ...

But did you know that there's more to light than meets the eye? Let’s explore the amazing world of the electromagnetic spectrum! The electromagnetic spectrum has many types of light waves. It includes ...

Harvard engineers unveiled the world's first visible-spectrum metasurfaces—ultra-thin, flat devices patterned with nanoscale ...

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explains how people see images, colour and even optical illusions. Lenses - Edexcel Lenses are ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. An object appears to be black if it absorbs all the wavelengths of visible light. For example ...

Olival Freire Jr is a professor of physics and the history of physics ... melting temperature or light-absorption spectra? Such questions exercised physicists greatly in the decades after Dmitri ...
