Show hintHide hint
Think of how waves add together when they align.
Question 2.
What is destructive interference?
Show hintHide hint
Consider what happens when peaks meet troughs.
3Question 3.
What is the phase difference for constructive interference?
- 0
- π
- π/2
Show hintHide hint
Think of how waves align.
4Question 4.
The resultant intensity in destructive interference will be?
- True
- False
Show hintHide hint
Recall the case of equal and opposite waves.
Question 5.
Two waves have intensities I1=5 and I2=3. Calculate their resultant intensity for constructive and destructive interference.
Show hintHide hint
Use the formulas for both cases appropriately.
Question 6.
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.
Show hintHide hint
Remember to relate the additional distance to the wavelength for phase calculations.
