Answer 1

Answer:

WAVE #3

Explanation:

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz

Answer 2

Answer:

C

Explanation:

The wavelength is the distance between the peak of one wave and the peak of a second wave. So 3 has the longest wavelength, and 2 has the shortest.
