Objects in space produce a variety of information in the form of signals of varying wavelengths. Many of these are invisible to the unaided eye, but provide important information on the objects that produce the radiation. This radiation can come in a number of forms, including visible light, X-rays, infrared, radio, and gamma radiation.

Telescopes that monitor energy with the longest wavelengths and do not need visible light or clear skies to operate are called _______________________ telescopes.

Select one:
a. refracting
b. invisible
c. radio
d. reflecting
