Suppose you are standing $225 \mathrm{~m}$ from a radio transmitter. What is your distance from the transmitter in terms of the number of wavelengths if
(a) The station is broadcasting at $1150 \mathrm{kHz}$ (on the AM radio band)? ( $1 \mathrm{kHZ}=1 \times 10^{3} \mathrm{~Hz}$ or 1000 cycles per second.)
(b) The station is broadcasting at $98.1 \mathrm{MHz}$ (on the FM radio band)? ( $1 \mathrm{MHz}=10^{6} \mathrm{~Hz}$, or cycles per second.)
