Answer:

Devices that produce a signal are used to indicate when different types of electromagnetic waves impinge on them.

Explanation:

Electromagnetic detection uses either passive or active detectors that indicate when a particular wavelength interacts with them. A radio receiver is one example of a passive detector. An interferometer may be either passive or active. Telescopes are passive visible light detectors.
