“The proposed optoacoustic (light+sound) entanglement scheme is based on Brillouin scattering. It is particularly resilient, ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to ...

Researchers have developed a highly sensitive detector for identifying molecules via their infrared vibrational "fingerprint.

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. Don't get confused with this quantity frequency. It is not a ...

Light changes speed as it passes from one medium to another. This is called refraction. The frequency of light does not change as it refracts. The refractive index of a material is a measure of ...

Supplier: Konica Minolta Sensing Americas, Inc. Description: The greater intensity and wider color gamut of OLED devices have created a need for a new level in measurement performance. The high ...

The different types of states are separated, and the high energy atoms decay to the low state, emitting light of the same characteristic frequency, which for cesium-133 atoms is precisely ...
