Females have, on average, 1 litter per year but can have 2 litters. Litters range in size from 2 to 8 offspring, unlike other members of the genus g. Lepus, of which the litters range from 1 to 4 offspring. The gestation period of Arctic hare is approximately 50 days, and offspring are usually born in May or June.Arctic hare weigh on average 105 g at birth.itters range in size from 2 to 8 offspring, unlike other members of the genus g.

Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz. With the use of antennas and transmitters, an RF field can be used for various types of wireless broadcasting and communications.
For other uses, see RF (disambiguation). Radio frequency (RF) is any of the electromagnetic wave frequencies that lie in the range extending from around 7003300000000000000â 3 kHz to 7011300000000000000â 300 GHz, which include those frequencies used for communications or radar signals. RF usually refers to electrical rather than mechanical oscillations.
