Challenge Problems
Push your limits with advanced challenges
Two waves have intensities I1=5 and I2=3. Calculate their resultant intensity for constructive and destructive interference.
💡 Hint: Use the formulas for both cases appropriately.
If a wave has a frequency of 500 Hz and a wavelength of 0.68 m, calculate the phase difference with another wave of the same frequency but with an additional path of 0.34 m.
💡 Hint: Remember to relate the additional distance to the wavelength for phase calculations.
