If you're preparing for university entrance exams and need to grasp the essentials of wave theory, you're in the right place.

You may be familiar with white noise, but what about pink noise, or brown noise? Turns out there is a rainbow of benefits for ...

Michelson built such an interferometer using the reasoning that the Earth was traveling through space — around the Sun — at about 30 km/s. Since the speed of light was 300,000 km/s, he ...

A research team in Korea has experimentally demonstrated, for the first time in the world, a nonlinear wave phenomenon that ...

Alternatively, you can ask, “what’s the frequency or the amplitude of this quantum,” and those are inherently wave-like properties. What you can’t do, though, is measure a particle-like ...

Sound and light have waves associated with them, so the analogy works: “Sound has a different distance to travel when the car comes towards you, instead of away from you,” Vitale tells Inverse.

“In the frequency approach, your qubit is a photon that can possess two different wavelengths, or colors of light simultaneously,” Lukens said. “A zero corresponds to one color, and one corresponds to ...
