The origin of a rainbow can be answered by almost everyone. We learn the physics behind a rainbow very early in our lives, but the phenomenon responsible for it does not linger in the minds of ...

The questions in this quiz are suitable for GCSE physics students who are studying reflection of waves and refraction of waves. If you struggled with the quiz, don't panic - we've got you! You can ...

Formulas Physics for Class 10: CBSE has released the 2025 date sheet for Class 10 and the practical viva along with pre-boards are already in the process. This is time that students start revising the ...

Save guides, add subjects and pick up where you left off with your BBC account. Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will ...

Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental ...

A U-rod in air transmits a laser beam like an optical fibre. When part of the rod is submerged in an index-matched mineral oil, the laser beam is no longer transmitted to the other end. Without ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...
