Waves Test

What is the ability to cause change?

• energy

• matter

• volume

Answer explanation

The ability to cause change is defined as energy. Energy is what enables work to be done and transformations to occur, making it the correct choice in this context.

What does a wave carry from place to place?

• energy

• matter

• people

Answer explanation

A wave carries energy from one location to another without transporting matter or people. This is evident in various types of waves, such as sound waves and electromagnetic waves, which transfer energy through different mediums.

The highest point on a transverse wave is the

• compression

• crest

• rest position

• trough

Answer explanation

The highest point on a transverse wave is called the crest. It represents the maximum displacement of the wave from its rest position, while the trough is the lowest point. Compression is a term used for longitudinal waves.

The lowest point on a transverse wave is the

• compression

• crest

• rest position

• trough

Answer explanation

The lowest point on a transverse wave is called the trough. It is the opposite of the crest, which is the highest point. Compressions and rest positions are terms related to longitudinal waves, not transverse waves.

The number of waves that pass somewhere in a second is:

• amplitude

• frequency

• wavelength

Answer explanation

Frequency refers to the number of waves that pass a point in one second. It is measured in hertz (Hz), making it the correct choice for this question, as amplitude and wavelength describe different wave properties.

A wave that can travel through matter and empty space is a:

• electromagnetic wave

• longitudinal wavy

• transverse wave

Answer explanation

An electromagnetic wave can travel through both matter and empty space, unlike longitudinal and transverse waves, which require a medium. This makes 'electromagnetic wave' the correct choice.

Which are properties of a mechanical wave?

• can be longitudinal or transverse

• can move through space

• must have matter to move

• carries energy

Answer explanation

Mechanical waves can be longitudinal or transverse, require matter to propagate, and carry energy. They cannot move through a vacuum, as they need a medium for transmission.

What are properties of electromagnetic waves?

• carry energy

• can move through space

• can move through matter

• include x-rays

Answer explanation

Electromagnetic waves have several key properties: they carry energy, can move through space, can also propagate through matter, and include various types such as x-rays. All these properties are essential to their behavior.

Which wave has the largest wavelength?

• A

• B

• C

• None (same wavelength)

Answer explanation

Wave B has the largest wavelength compared to A and C. Wavelength is inversely related to frequency, and since B is identified as having the largest wavelength, it is the correct choice.

Waves that require a material to travel though are called

• electromagnetic waves

• mechanical waves

• ocean waves

• transverse waves

Answer explanation

Waves that require a material to travel through are known as mechanical waves. Unlike electromagnetic waves, which can travel through a vacuum, mechanical waves need a medium such as air, water, or solids.
