Card 1
Question: What are waves, and how do they transfer energy?
Answer: Waves are disturbances that transfer energy without transferring matter.
Card 2
Question: What are the two main types of waves based on oscillation direction?
Answer: Transverse waves and longitudinal waves.
Card 3
Question: Describe a transverse wave.
Answer: The oscillation is perpendicular to the direction of wave propagation (like waves on a string).
Card 4
Question: Describe a longitudinal wave.
Answer: The oscillation is parallel to the direction of wave propagation (like sound waves in air).
Card 5
Question: What kind of waves are primarily dealt with in string instruments?
Answer: Transverse waves.
Card 6
Question: What happens when a wave on a string fixed at both ends reflects off the ends?
Answer: The reflected wave travels back along the string, interfering with subsequent waves.
Card 7
Question: What special condition can continuous interference of waves on a string lead to?
Answer: A standing wave.
Card 8
Question: What is a standing wave?
Answer: A standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space.
Card 9
Question: When does a standing wave occur?
Answer: It occurs when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and superimpose.
Card 10
Question: What is a crucial condition for a standing wave to form on a string fixed at both ends?
Answer: The ends of the string must remain stationary.
