Two transmitters send coherent signals to a mobile hand-held receiver as shown in the figure. One signal travels a distance, d₁ = 35 km, and the other travels a distance, d₂ = 72.5 km,. The two signals, which have a frequency of 120-kHz, were in phase when they left the transmitters so the question is, will they still be in phase when they reach the receiver? d₁ d₂

Question
Transcribed Image Text:Two transmitters send coherent signals to a mobile hand-held
receiver as shown in the figure. One signal travels a distance,
d₁ = 35 km, and the other travels a distance, d₂ = 72.5 km,.
The two signals, which have a frequency of 120-kHz, were in
phase when they left the transmitters so the question is, will
they still be in phase when they reach the receiver?
Transcribed Image Text:The mobile receiver moves to a new location so that d₁ = 46.25 km, and d₂ = 68.75 km.
(c) How many wavelengths does each signal travel now?
d=1
The two signals will therefore interfere ---Select---
---Select---
constructively
destructively
