Range of NDB at 10kw;(wat is the formula to calculate it...)
a)500nm b)100nm c)1000nm d)50 nm
range of ndb over water(nm)=3xsqroot(power in watts)
range of ndb over land(nm)=2xsqroot(power in watts)
if we use these formulas the answers are 200nm and 300nm respectively....and none of these are given in the options.........guys please let me know if am going wrong somewhere or if there is a different formula for it...thanks in advance
