Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can ...

In the future, this method could also be used in technical applications with electromagnetic waves. Water, light and sound ...

Researchers at ETH Zurich have created a T-shirt that can measure breathing and gloves that can translate hand movements into ...

Here we use photonics, or light energy, to produce the sound wave. This approach has multiple advantages, chief of which is that light does not produce the heat in the chip that electronic ...

With advanced technology and artificial intelligence, we are now able to listen to these cosmic whispers in ways that were ...

5. Encourage students to think about other kinds of energy that travel in the form of waves (e.g. sound, light). Explain to students when a train whistle screams, the sound they hear has moved ...
