Constructive & Destructive Interference

What happens to the amplitude of a wave during destructive interference?

• The amplitude of the resulting wave increases.

• The amplitude of the resulting wave remains the same.

• The amplitude of the resulting wave decreases during destructive interference.

• The amplitude of the resulting wave becomes zero.

What is the principle of superposition in wave interference?

• The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.

• The principle of superposition states that waves can only interfere constructively.

• The principle of superposition states that waves cannot pass through each other.

• The principle of superposition states that the speed of a wave is constant regardless of the medium.

What is the role of noise-cancelling headphones in terms of interference?

• They amplify ambient sounds to enhance listening experience.

• They use destructive interference to reduce unwanted ambient sounds by producing sound waves that are out of phase with the noise.

• They create a sound barrier to block all external noise.

• They convert sound waves into electrical signals for better clarity.

How do sound waves from wind instruments demonstrate constructive interference?

• When sound waves from wind instruments combine in phase, they amplify the sound, resulting in louder music.

• When sound waves from wind instruments are out of phase, they cancel each other out, resulting in quieter music.

• When sound waves from wind instruments travel at different speeds, they create a dissonant sound.

• When sound waves from wind instruments are reflected off surfaces, they create echoes.

What is Destructive Interference?

• Destructive interference occurs when two or more waves combine to produce a wave of greater amplitude.

• Destructive interference occurs when two or more waves combine to produce a wave of lesser amplitude. This happens when the crest of one wave aligns with the trough of another.

• Destructive interference is the phenomenon where waves completely cancel each other out, resulting in no wave at all.

• Destructive interference occurs when waves are in phase, leading to an increase in amplitude.

True or False: Electromagnetic waves travel faster through solids than gases.

• True

• False

• Electromagnetic waves travel faster in gases than in a vacuum.

• Electromagnetic waves travel at the same speed in solids and gases.

What is the difference between a wave's frequency and its wavelength?

• Frequency is the distance between successive crests or troughs of a wave, while wavelength is the number of waves that pass a point in one second.

• Frequency is the number of waves that pass a point in one second, while wavelength is the distance between successive crests or troughs of a wave.

• Frequency and wavelength are the same thing, just measured in different units.

• Frequency is the speed of the wave, while wavelength is the amplitude of the wave.

What happens to the amplitude of a wave during constructive interference?

• The amplitude of the resulting wave decreases during constructive interference.

• The amplitude of the resulting wave remains the same during constructive interference.

• The amplitude of the resulting wave increases during constructive interference.

• The amplitude of the resulting wave fluctuates randomly during constructive interference.

What is a standing wave?

• A wave that travels in one direction only.

• A wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.

• A wave that increases in amplitude over time.

• A wave that is created by a single source without interference.

What creates a wave?

• A wave is created by a force that causes a disturbance in a medium, such as air or water.

• Waves are formed by the interaction of light and sound.

• A wave is created by the movement of particles in a vacuum.

• Waves are generated by electrical impulses in the atmosphere.
