Will shouts "Hello" in a canyon. The sound bounces back to him as an echo. This is an example of a wave
-
Being reflected
-
Being refracted
-
Being diffracted
-
Interfering with another wave
Correct Answer
A. Being reflectedExplanation
When Will shouts "Hello" in a canyon, the sound waves travel through the air and hit the canyon walls. The sound waves then bounce back towards Will, creating an echo. This process is known as reflection, where the sound waves are redirected back towards the source. Therefore, the correct answer is "being reflected."Rate this question:

At the beach, Paula measures how many wave crests reach the shore in a given time. She is finding the wave;s
-
Amplitude
-
Frequency
-
Speed
-
Wavelength
Correct Answer
A. FrequencyExplanation
Paula is measuring the number of wave crests that reach the shore in a given time. The frequency of a wave refers to the number of complete wave cycles that occur in a given time period. Therefore, Paula's measurement of the number of wave crests reaching the shore corresponds to the frequency of the waves.Rate this question:

Forces can cause waves by
-
Canceling them out
-
Moving large amounts of matter
-
Creating disturbances
-
Providing a medium
Correct Answer
A. Creating disturbancesExplanation
Forces can cause waves by creating disturbances. When a force is applied to a medium, it can disrupt the equilibrium and create a disturbance in the form of a wave. This disturbance travels through the medium, causing particles to move in a wave-like motion. The force can be applied directly to the medium, such as when a person throws a stone into a calm pond, or indirectly, such as when wind blows over the surface of water, creating waves. In either case, the force creates a disturbance that propagates as a wave.Rate this question:

Martin wants to know the wavelength of the wve made when he dips his finger into a pond. What should he measure?
-
The speed at which the wave travels
-
The number of troughs he sees in one second
-
The height of each crest
-
The distance between one trough and the next
Correct Answer
A. The distance between one trough and the nextExplanation
To determine the wavelength of a wave, Martin should measure the distance between one trough and the next. The wavelength is the spatial period of a wave, representing the distance between two consecutive points with the same phase, such as two adjacent troughs or crests. By measuring the distance between troughs, Martin can determine the length of one complete wave cycle, which is the wavelength.Rate this question:

A wave has a wave length of 20 m and a frequeny of 4 wavelengths/s. What is the wave's speed?
-
5 m/s
-
16 m/s
-
24 m/s
-
80 m/s
Correct Answer
A. 80 m/sExplanation
The speed of a wave can be calculated by multiplying its wavelength by its frequency. In this case, the wavelength is given as 20 m and the frequency is given as 4 wavelengths/s. Multiplying these values together gives us a speed of 80 m/s.Rate this question:

Roads can be bent or broken far away from an earthquake;s center. This shows that earthquake waves
-
Move rocks away from the center
-
Are longitudinal waves
-
Raise and lower the ground level near the center
-
Transfer energy over a distance
Correct Answer
A. Transfer energy over a distanceExplanation
The fact that roads can be bent or broken far away from an earthquake's center suggests that earthquake waves transfer energy over a distance. This is because the energy carried by the waves causes the ground to shake and can cause damage to structures even at a significant distance from the epicenter.Rate this question:

Refractions happens when a wave
-
Strikes a barrier
-
Passes through a small opening
-
Meets another wave
-
Moves from one medium to another
Correct Answer
A. Moves from one medium to anotherExplanation
Refractions occur when a wave transitions from one medium to another. As it moves from a medium with one set of properties to a medium with different properties, such as a change in density or composition, the wave changes direction. This change in direction is caused by the change in speed of the wave as it enters the new medium. Therefore, the correct answer is "moves from one medium to another."Rate this question:

Ronda put two speakers in her room. In one place, the sound was much quieter than in the rest of the room. What might cause this?
-
Constructive interference
-
Destructive interference
-
Diffraction
-
Reflection
Correct Answer
A. Destructive interferenceExplanation
Destructive interference occurs when two sound waves meet and their crests and troughs align, causing them to cancel each other out. In this scenario, it is likely that the two speakers are producing sound waves that are out of phase with each other, resulting in areas of quiet sound where the waves are canceling each other. This explains why the sound is much quieter in one place compared to the rest of the room.Rate this question:

One example of diffraction is a
-
Wave in a pond spreading as it passes a rock
-
Light wave bouncing off a mirror
-
Speaker producing sound waves
-
Straw in a glass of water appearing to be split
Correct Answer
A. Wave in a pond spreading as it passes a rockExplanation
Diffraction refers to the bending or spreading of waves as they encounter an obstacle or pass through an opening. In the given options, the only example that demonstrates this phenomenon is a wave in a pond spreading as it passes a rock. As the wave encounters the rock, it will diffract or spread outwards, creating a pattern of ripples around the obstacle. This is a clear example of diffraction, while the other options do not involve the bending or spreading of waves.Rate this question:
