What is the difference between a shortwave and a longwave?
What does longwave mean?
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band.
A longwave radio tunes into longwave radio signals with low frequencies ranging between 30 and 279 kHz. On the other hand, shortwave radios tune into shortwave radio signals with higher frequencies ranging between 3 and 30 MHz (3,000 and 30,000 kHz).

Apr 4, 2023 · Longwaves and Shortwaves. The hemispheric weather patterns are governed by mid-latitude (23.5°N/S to 66.5°N/S) westerly winds which move in large wavy patterns. Known as planetary waves, these longwaves are also called Rossby waves, named after Carl Rossby, who discovered them in the 1930s.
In climate science, longwave radiation ( LWR) is electromagnetic thermal radiation emitted by Earth's surface, atmosphere, and clouds. It may also be referred to as terrestrial radiation. This radiation is in the infrared portion of the spectrum, but is distinct from the shortwave (SW) near-infrared radiation found in sunlight. [1] : 2251.
May 24, 2024 · Longwave radiation. The energy absorbed by the surface is radiated from the Earth as terrestrial longwave radiation (L↑). The amount of energy emitted is primarily dependent on the temperature of the surface. The hotter the surface the more radiant energy it will emit.
Aug 10, 2016 · Heat resulting from the absorption of incoming shortwave radiation is emitted as longwave radiation. Radiation from the warmed upper atmosphere, along with a small amount from the Earth's surface, radiates out to space.
Jul 21, 2020 · The color red is made of light waves similar in length to that of infrared waves (or heat), which is why hot things appear red. X-rays, UV light and the colors purple and blue have shorter wavelengths. Radio waves, microwaves, infrared and the colors red and orange have longer wavelengths.
