a: Wavelength ~
b: the distance between two wave crests on the ocean
What:
"Radio energy moves in waves, and each radio wave has not only a frequency but also a wavelength. The wavelength is like the distance between two wave crests on the ocean. With radio energy, the wavelength of a radio wave multiplied by its frequency is equal to the speed of light: 3x108
meters per second (roughlyequal to 186,000 miles per second). The size of waves for each of the unlicensed bands is presented in Table 2.3"
