Waves #2 Assignment MC

Which of the following is an example of waves adding together so that the combined amplitude is LARGER. (Think about what type of pulse and in what direction they would be travelling?)

• 
• 
• 
• 

If 2 waves are adding together so that the combined amplitude is LARGER, what type of interference is it?

• constructive

• destructive

When water waves crash against a cliff, the incoming waves interfere with the reflected waves creating standing waves. Taking into account that this is a standing wave, what would you see IN THE WATER that indicates constructive interference is occurring?

• no waves

• smaller waves

• larger waves

When water waves crash against a cliff, the incoming waves interfere with the reflected waves creating standing waves. Taking into account that this is a standing wave, what would you see IN THE WATER that indicates destructive interference is occurring?

• no waves

• smaller waves

• larger waves

Which way does the reflected pulse return?

• same side

• opposite side

Describe the speed of the reflected pulse compared to the incident pulse.

• faster

• slower

• the same

Describe the wavelength of the reflected pulse compared to the incident pulse.

• longer

• shorter

• the same

At which section(s) are the reflected pulses inverted?

• A

• B

• both A & B

• Neither A nor B

Which rope will produce the fastest moving wave?

• Thin (less dense)

• Thick (more dense)

Which rope will produce the wave with the longer wavelength?

• Thin (less dense)

• Thick (more dense)
