use c=#nulambda#

Explanation:

c=#nulambda# #implieslambda=c/nu#
here, c=speed of signal(em wave)= #3*10^8ms^-1#
#nu#=frequency of signal=500kHz=#5*10^5Hz#
#therefore#wavelength of signal=#lambda#=#3*10^8/(5*10^5)m#
given that, length of antenna=#lambda/4#=#1/4*{3*10^8/(5*10^5)}m#=#3*10^2/2m#=#300/2m#=#150m#
