Both. There are BANDS of frequencies set
aside for Amateur use. Some bands use
low frequencies – these are long waves,
longer than a house – and some use high
frequencies. Some Amateur waves are
so small they are called
Radio is part of the electromagnetic spectrum, just
like x-rays and light. All electromagnetic energy
travels in waves at the speed of light. The
the wavelength, the
the frequency and the
shorter the wavelength the higher the frequency.
So are Amateur Radio waves longer or
shorter than one’s received by my radio?

Hz stands for
and is named after the German scientist Heinrich Hertz who discovered
electromagnetic waves – at first called Hertzian Waves.
A frequency of 1 Hz is one wave per
second, 1 KHz is one thousand per second, 1 MHz is 1 million, and 1 GHz a thousand million.
