Lower the frequency higher the wavelength
High frequency less power short distance
Low frequency less power short distance

Any region between Point A to B(wavelength) of the low frequency is called dead zone i.e no radio signal is received in such region
Heat beats at a frequency of 120 times a min. Its period is half a second.
60/120 = 0.5 sec
period = interval between two beats.
