Resultant Intensity of Water-waves

Click For Summary
SUMMARY

The discussion centers on calculating the resultant intensity of water-waves generated by two wave generators, S1 and S2, positioned 4 meters apart. When operating individually, S1 produces an intensity of I and S2 produces 3I at point P, which is located 3 meters from S1 and 5 meters from S2. When both generators operate in phase, the resultant intensity at P is determined to be 7.5I, based on the principle of superposition of wave intensities.

PREREQUISITES
  • Understanding of wave interference principles
  • Knowledge of intensity calculations in wave mechanics
  • Familiarity with the concept of phase in wave propagation

Homework Statement


Two wave generators S1 and S2 produce water-waves of wavelength 4m. They are placed 4m apart in a water tank and a detector P is placed on the water surface 3 m from S1. (90 degree to S1S2, S2 to P is 5m)

When operted alone, S1 and S2 produce waves with intensity I and 3I at P respectively. When the generators are operating together and in phase, what is the resultant intensity at P?


Homework Equations

Well, what do you think? Hint: Are the waves at P in phase, out of phase, or what?
