The equation needed when studying waves is: wave speed = frequency x wavelength. A ripple tank allows you to study transverse waves in water. Ripple tanks vary a lot in how they look, but usually ...

Researchers in the UK have developed a new spray coating for greenhouses that optimizes the wavelength of light shining onto the plants, improving their growth and yield. The technology could in ...

The very broad bandwidth of low-loss optical transmission in a single-mode fiber and the recent improvements in single-frequency tunable lasers have stimulated significant advances in dense wavelength ...

Abstract: This paper reports measurements of the permittivity of moist air under different conditions of pressure, temperature, and water-vapor content taken at a frequency of 3,036 Mc. The method and ...

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

A Japanese research team led by Professor Hidetoshi Katori at The University of Tokyo, has achieved a groundbreaking ...

Researchers in China have harnessed the power of the Doppler effect to achieve a breakthrough in submarine detection.

Sub-wavelength optics is the study of light on a spatial scale smaller than its wavelength. Conventionally, the minimum length scale on which a beam of light can operate is equal to half its ...

Most people know that one of the best ways to treat mold on a household item like a blanket or piece of upholstered furniture ...

Researchers have defined the precise shape of a single photon, a huge leap forward in quantum physics and material science.

Some of the energy is lost to space while some is returned to Earth. NOAA’s Global Monitoring Laboratory reported in January ...
