This quiz checks for understanding of some basic knowledge and concepts associated with waves.

• 1.

The most common motion in the universe is

• A.

Rectilinear motion.

• B.

Free range motion.

• C.

Periodic motion.

• D.

Locomotion.

C. Periodic motion.
Explanation
Periodic motion refers to the repetitive motion of an object or system that repeats itself after a certain time interval. This type of motion is commonly observed in various natural phenomena, such as the swinging of a pendulum, the motion of planets around the sun, or the vibrations of a guitar string. It is considered the most common motion in the universe because many objects and systems exhibit periodic behavior, making it a fundamental concept in physics and other scientific disciplines.

What is the wave behavior illustrated below?

• A.

Refraction

• B.

Diffraction

• C.

Reflection

• D.

Interference

C. Reflection
Explanation
The wave behavior illustrated in the given image is reflection. Reflection occurs when a wave encounters a boundary and bounces back, changing direction. In the image, the wave is shown hitting a surface and bouncing off of it, indicating reflection.

In the playground, Jill's sister pushes her back and forth 20 times per minute on the swing.  What is the period of Jill's swinging motion?

• A.

0.05 seconds

• B.

3 seconds

• C.

5 seconds

• D.

20 Hz

B. 3 seconds
Explanation
The period of Jill's swinging motion is 3 seconds. The period is the time it takes for one complete cycle of motion to occur. In this case, Jill's sister pushes her back and forth 20 times per minute, which means that one complete cycle of Jill swinging takes 3 seconds (60 seconds divided by 20 swings). Therefore, the correct answer is 3 seconds.

Rate this question:

• 4.

When the frequency of a wave increases, then

• A.

The speed of the wave increases.

• B.

The amplitude of the wave increases.

• C.

The wavelength remains constant

• D.

The speed of the wave remains constant

D. The speed of the wave remains constant
Explanation
When the frequency of a wave increases, the speed of the wave remains constant. The speed of a wave is determined by the medium through which it travels, and it is not affected by the frequency of the wave. The frequency of a wave refers to the number of complete cycles of the wave that occur in a given amount of time. Therefore, increasing the frequency does not change the speed at which the wave travels.

Rate this question:

• 5.

As a water waves travels left to right,

• A.

The water moves left to right

• B.

The water moves up and down

• C.

The water remains undisturbed

• D.

No energy is transferred

B. The water moves up and down
Explanation
As a water wave travels left to right, the water molecules are not fixed in place but instead move in a circular motion. This circular motion causes the water to move up and down as the wave passes through. Therefore, the correct answer is that the water moves up and down.
