Homework Statement
Radio waves (speed=c) from a two point source produce an interference pattern in space. Your house is located at a point where the path difference from the two radio sources is 1500 m. If the radio frequency is 500 kHz, show whether your house is on a node or an antinode. Answer =node, lousy reception
Homework Equations
C=λf
3.The attempt at a solution
I figured out the lamda by dividing C by f first and it came out to be 600m , but 1500m is not a COMPLETE divisible of 600m and results in N being = 2.5 which means that it should be an antinode however the answer says that its a node, am I doing something wrong? Please help. Thank you :)
