U4.3 - 2 - características de una onda-Superposition of Waves

What is the superposition of waves?

• When waves bounce off each other

• When waves interact and change direction

• When waves are in the same physical location and their amplitudes add together

• When waves cancel each other out

What happens to the amplitudes of waves in superposition?

• They subtract from each other

• They multiply with each other

• They add together to produce a single wave

• They remain unchanged

What happens to waves after they are in superposition?

• They bounce off each other

• They continue to move as if they never interacted

• They change direction

• They combine to form a new wave

What is constructive interference?

• When two waves cancel each other out

• When two waves add together to produce a larger amplitude

• When two waves change direction

• When two waves bounce off each other

What is destructive interference?

• When two waves add together to produce a larger amplitude

• When two waves change direction

• When two waves cancel each other out

• When two waves bounce off each other

What happens when a wave has a negative amplitude in superposition?

• It adds positively to the total amplitude

• It subtracts from the total amplitude

• It cancels out the positive amplitude

• It has no effect on the total amplitude
