The questions in this quiz are suitable for GCSE physics students studying convex and concave lenses, real and virtual images, magnification and colour. If you struggled with the quiz, don't panic ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Scientists have developed an impossibly thin telescope lens that addresses a key astronomical challenge in a new study funded ...

For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be ...

Time travel has captivated our imagination for decades, but what does physics say about its possibility? Groundbreaking theories from Einstein’s relativity challenge our conventional ...

For the first time, a flat telescope lens has been produced that represents colors accurately, offering a way to make less bulky lenses that could be sent into space cheaply. The first telescopes ...
