but with different wavelengths (frequencies) and different made-up names.

Mount Etna is Europes most active volcano and was last active in 2008. Check the related link for a video of this.
Our Milky Way has a supermassive black hole at its nucleus. It is an active radio source. It is probably not a Seyfert galaxy, which is a galaxy of a type characterized by a bright compact core that shows strong infrared emission, though.

An infrared detector needs a power source to operate and it is used to active a relay that can be used as a switch.
Potassium fluoride isn't used in infrared spectroscopy.
Microwaves have lots of uses, some commercial (such as microwave ovens, satellite TV, and weather radar) and some military (such as missile guidance systems), applications in the field of scientific research, microwaves monitor the environmental health of our planet as well as to learn more about the universe. Research scientists use microwaves in two types of systems: active and passive. In active systems, such as radars, scientists send out microwaves and examine what comes back. In passive systems scientists simply look for naturally occurring microwaves and use them to learn more about the objects that emit the waves.
Infrared lamps are electrical devices that use infrared LEDs to emit infrared radiation everywhere. Many studies show that this warm infrared radiation plays an active role in providing health and well-being to people. It increases activity, stimulates cellular energy production and cell regeneration, and promotes relaxation in the body.
An active worksheet is a spreadsheet that is visible in a workbook. When you open a new workbook, the first sheet you see is the active worksheet.

Your places are visible to the community by default. If your place is not visible you can make it visible by clicking "My Roblox", then "Places" then clicking make active next to your place. If you had Builders-club and lost it you can only have one active place at a time.
by active but when your active you have to be responsible for your actions
You generally can't. There aren't any visible signs of being sexually active or not being sexually active, unless you see them in the act.
Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
