Scientists have been unable to confirm the existence of time reflection due to the amount of energy required to create a temporal interface. Using an engineered metamaterial scientists in New York ...

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 ...

Bengaluru: Indian Institute of Science (IISc) researchers have developed a non-invasive technique to measure blood glucose ...

By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

In the future, this method could also be used in technical applications with electromagnetic waves. Water, light and sound waves usually propagate in the same way forward as in a backward direction.

For centuries, the reflections of light or sound have been theorized. Scientists have always thought of another variable: that of time. Many claim that temporal reflections are pos ...

Blood glucose is usually measured using invasive methods involving pricking small needles into the skin. But people suffering ...

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 ...
