Which band of the electromagnetic spectrum has the lowest frequency?

Radio waves

Explanation:

Electromagnetic waves are waves produced by the oscillations of electric and magnetic fields. Electromagnetic waves are the only type of waves that can propagate through a vacuum also, since they do not need a medium to travel through.

Electromagnetic waves are classified based on their frequency, since electromagnetic waves with different frequencies have different properties. From the lowest frequency to the highest frequency, they are:

Radio waves

Microwaves

Infrared waves

Visible light

Ultraviolet

X-rays

Gamma rays

So, the part of the electromagnetic spectrum that has the lowest frequency corresponds to the radio waves. Radio waves have low frequency, between 30 Hz and 30 GHz, and are used for long-distance transmissions, like radio communications, broadcasting, satellites, etc.
