Electromagnetic energy (which includes radio waves) travels at 2.998... x 10^10 cm/sec ... 3.0 x 10^ 10 cm/sec is close enough. (3.0 x 10^10 = 3.0 x 10,000,000,000 cm/sec = 30,000,000,000 cm/sec.
102.1 Hz = 102.1 cycles per second... which is awfully slow (perhaps you meant 102.1 MHz or 102.1 million Hz or 102.1 x 10^6 HZ = 102,100,000 Hz = 102,100,000 cycles per second?)
In any case, divide the speed by the frequency to get the wavelength. Thus,
30,000,000,000 cm/sec /102.1 cycles/sec = 30,000,000,000/102.1 cm/cycle =~2,937,000,000 cm/cycle or 29,370,000 meters/cycle or 29,370 km/cycle
If the frequency is 102.1 MHz, then you get a wavelength which is one millionth as long or 2,937 cm/cycle or 29.37 meters/cycle.
