Identify the labeled part numbered 2 of the transverse wave.

• Crest

• Trough

• Amplitude

• Rest Position

• Wavelength

Answer explanation

The labeled part numbered 2 in a transverse wave represents the wavelength, which is the distance between two consecutive crests or troughs. It is a key characteristic of wave behavior.

Identify the labeled part numbered 3 of the transverse wave.

• Crest

• Trough

• Amplitude

• Rest Position

• Wavelength

Answer explanation

The amplitude of a transverse wave is the distance from the rest position to the crest or trough. It represents the wave's height, making 'Amplitude' the correct answer for part numbered 3.

Identify the labeled part numbered 4 of the transverse wave.

• Crest

• Trough

• Amplitude

• Rest Position

• Wavelength

Answer explanation

The labeled part numbered 4 in a transverse wave is the trough, which is the lowest point of the wave. The crest is the highest point, while amplitude refers to the height from the rest position to the crest or trough.

Identify the labeled part numbered 5 of the transverse wave.

• Crest

• Trough

• Amplitude

• Rest Position

• Wavelength

Answer explanation

The labeled part numbered 5 in a transverse wave represents the Rest Position, which is the equilibrium state of the wave where it would be if there were no disturbances. It is the baseline from which the wave oscillates.

Which of the following is a type of wave?

• Seismic

• Frequency

• Amplitude

• Trough

Answer explanation

Seismic waves are a type of wave that travels through the Earth, typically generated by geological events like earthquakes. Frequency and amplitude are properties of waves, while trough refers to a specific point in a wave.

What does point A represent?

• Crest

• Trough

• Rarefaction

• Compression

Answer explanation

Point A represents compression, which is the region in a wave where particles are close together. This is in contrast to rarefaction, where particles are spread apart, and does not correspond to crest or trough.

Transverse waves have

• Crest

• Trough

• Rarefaction

• Compression

Answer explanation

Transverse waves are characterized by their crests (the highest points) and troughs (the lowest points). Unlike longitudinal waves, they do not have rarefactions or compressions.

Longitudinal waves have

• Crest

• Trough

• Rarefaction

• Compression

Answer explanation

Longitudinal waves consist of compressions and rarefactions. Compressions are regions where particles are close together, while rarefactions are areas where they are spread apart. Thus, the correct answers are rarefaction and compression.

A pencil looks cut when placed in water.  Which word describes this? 

• reflection

• refraction

• diffraction

• interference

Answer explanation

The pencil appears cut when placed in water due to refraction, which is the bending of light as it passes from air into water. This optical phenomenon causes the pencil to look displaced at the water's surface.

Disturbances that carry energy through matter or space are called

• crests

• energy

• waves

• troughs

Answer explanation

Disturbances that carry energy through matter or space are known as waves. They can be seen in various forms, such as sound waves or light waves, making 'waves' the correct answer.
