Stationary waves...
Which of the following equations can form stationary waves...
1. y=Asin(wt-kx)
2. y=Acos(wt-kx)
3. y=Asin(wt+kx)
4. y=Acos(wt+kx)
Answer is 1,3 and 2,4 which is obviously correct...But why can't other combinations be possible as long as they are traveling in opposite directions (like 2 and 3)?
And you can standing waves be formed by waves of different amplitudes?
