Semester 2 Review

What does "Amplitude" refer to in the context of ocean waves?

• The time it takes for a wave to travel from one peak to the next
• The number of waves passing a fixed point in a set period of time
• The highest and lowest points of the waves on a graph
• The maximum height of a wave from its rest position

What happens to a child's speed on a swing as they reach the highest point of the swing?

• Gainds velocity
• Becomes zero
• It loses velocity
• It remains constant

Imagine you are at the beach, watching waves travel towards the shore. In this scenario, what plays the role of a medium for these waves?

• The initial source of the wave
• The sandy shore that the waves crash into
• The water through which the wave travels
• The frequency at which waves come

Imagine you're an astronaut in space, far away from Earth. Which type of wave can still reach you without needing a medium like air or water?

• Sound waves
• Electromagnetic Radiation
• Water waves
• Mechanical Waves

When you see waves approaching the shore at the beach, what are they primarily transporting?

• Matter
• Particles
• Energy
• Heat

At a rock concert, which of the following is an example of a mechanical wave?

• Sound waves
• Gamma Rays
• Light Waves
• X-rays

During a calm sea day, what is the term used to describe the highest point a surfer reaches on a wave before it breaks?

• Trough
• Frequency
• Amplitude
• Crest

Imagine you're observing the ocean waves from the beach. What is the name of the lowest point you see in a wave, below the line where the water would be calm and flat?

• Crest
• Trough
• Equilibrium position
• Wavelength

In a music studio, how is the pitch of a note typically measured?

• Meters
• Hertz
• Cycles
• Seconds

When Zander stands 120 meters away from a canyon wall and shouts, why is the sound wave said to be traveling double the distance?

• Because the sound wave travels to the wall and then back to Zander
• Because the canyon wall doubles the speed of the sound wave
• Because the sound wave gets louder as it travels
• Because the echo takes twice as long to return
