Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
Passive.
It can be either. A carrier pigeon is active whereas a malaria mosquito is passive.
it is active
Osmosis is an example of Passive Transport.
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
A mapmaker might use active remote sensing over passive remote sensing because active remote sensing provides its own source of energy to illuminate the target, allowing for more control over the data collected. This can result in better resolution and accuracy in mapping features of interest.
Passive remote sensing picks up wave lengths of the light spectrum occurring on their own such light in photography. Active remote sensing will send out a wavelength of the spectrum and measure how it bounces back like radar.
Active remote sensing uses its own energy source to illuminate the target and measure the reflected signals, such as radar. Passive remote sensing relies on external energy sources, like the sun, and measures the natural radiation emitted or reflected by the target, such as with optical sensors.
Active remote sensing transmits energy to allow an image to be formed. Passive remote sensing collects energy reflected or emitted from a surface. Active systems direct a bean of energy at a surface and analyze the energy reflected back. An example of active sensing would be a radar. Passive systems are pretty much what the eyes see, and it's like a photograph. Passive sensing radiates visible light.
I broke my leg. (active voice) My leg is broken. (passive voice) Active voice vs. Passive voice.
Active voice should be used instead of passive voice when the focus is on the subject performing the action, rather than the action being done to the subject.
passive
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).
Three types of remote sensing are passive remote sensing (detects natural radiation emitted or reflected by objects), active remote sensing (sends out its own radiation to illuminate objects), and aerial photography (capturing images of the Earth's surface from aircraft or satellites).

is a thermocouple an active or passive transducer?-why?
