Intensity (physics)
In physics, intensity is the power transferred per unit area, where the area is an imagined surface that is perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m2). It is used most frequently with waves (e.g. sound or light), in which case the average power transfer over one period of the wave is used. Intensity can be applied to other circumstances where energy is transferred. For example, one could calculate the intensity of the kinetic energy carried by drops of water from a garden sprinkler.
The word "intensity" as used here is not synonymous with "strength", "amplitude", "magnitude", or "level", as it sometimes is in colloquial speech.
Intensity can be found by taking the energy density (energy per unit volume) at a point in space and multiplying it by the velocity at which the energy is moving. The resulting vector has the units of power divided by area.
Mathematical description
If a point source is radiating energy in all directions (producing a spherical wave), and no energy is absorbed or scattered by the medium, then the intensity decreases in proportion to distance from the object squared. This is an example of the inverse-square law.
Intensity (Art Pepper album)
Intensity is a 1960 jazz album by saxophonist Art Pepper playing with Dolo Coker, Jimmy Bond and Frank Butler. The album was released in 1963.

Zki & Dobre, known by many aliases, but currently most well known as Chocolate Puma (alternatively as The Good Men and as The Goodmen), are a Dutch house music duo from Haarlem, Netherlands. They comprise Gaston Steenkist ("Dobre") and René ter Horst ("DJ Zki"). They have produced multiple dance hits under various group names since the early 1990s. Their biggest international hits remains "Give It Up in 1993 credited as The Good Men and "Who Do You Love Now?" in 2001 credited to Riva featuring Dannii Minogue. They also founded their own record label Pssst Music.
Career
As the Goodmen, their biggest hit was "Give It Up", a 1993 house music track based upon samba styled percussion and the simple, repeating vocal line of the song title. The percussion for the release was inspired by an earlier recording by Sérgio Mendes.
The song hit #1 on the US Billboard Hot Dance Club Play chart in 1993 and made a brief appearance on the US Billboard Hot 100 chart, peaking at #71. After being re-released in late 1993, it reached #5 in the UK Singles Chart.
Riva (band)
Riva was a pop rock band from Zadar, Croatia, then Yugoslavia, in the late 1980s.
After forming in 1986, the band appeared on Zagrebfest 1988. Their song "Rock Me" won the Eurovision Song Contest 1989 in Switzerland, with a score of 137 points. According to author John Kennedy O'Connor in The Eurovision Song Contest – The Official History it was an unexpected win. The band proved sceptics wrong bringing the first and only victory for Yugoslavia. The contest was organised in Zagreb in 1990. The group members parted ways in 1991.
