In open space, infinitely far from material objects, the radiation pattern of a half-wave
dipole is a torus (donut), with the radiator (wire) passing straight through the center
of the hole. The field strength is maximum in all directions perpendicular to the wire,
and zero in the directions off the ends of the wire. The peak field strength is +2.2 dB
relative to isotropic.

Radiation resistance of folded dipole?
4*73=292 dattatreya
Why do polar molecules absorb IR?
You can view incident IR radiation as an oscillating electric field ( the 'wave-like' view of EM radiation.) As such, it effects the vibration of a molecule by inducing a dipole oscillation of the same frequency. The connection is most clearly seen if you consider that the induced dipole oscillation produces an identical oscillating electric field to the field that induced it. A molecule can only produce an oscillating electric field by vibration if its vibration produces a change in dipole moment (a non-polar molecule would produce a constant electric field regardless of the vibration.) I hope that helps
Does your hand emit long or short wave radiation and how do you know?
Long wave radiation in the form of infrared waves. These can be seen with an infrared camera.
How do you determine the molecule is microwave active or inactive?
It is determined by whether the molecule is polar or nonpolar. Nonpolar molecules do not absorb radiation in the microwave region; therefore, they are microwave inactive. Polar molecules are microwave active.
