A visible band image of Jupiter is shown below the radio image. Radio telescopes are much larger than optical telescopes because radio wavelengths are much longer than optical wavelengths. The longer wavelengths means that the radio waves have lower energy than optical light waves. In order to collect enough radio photons to detect a signal, the radio dishes must be very large.
Radio Signal Interference. The process of transmitting and receiving radio and laser signals through the air makes wireless systems vulnerable to atmospheric noise and transmissions from other systems. In addition, wireless networks can interfere with other nearby wireless networks and radio wave equipment. Interference can take on an inward or outward direction.
