Question 1: Crest

Answer:

The high part of a transverse wave.

Question 2: Transverse Wave

Answer:

Waves that move the medium at right angles to the direction in which the waves travel.

Question 3: Diffraction

Answer:

When a wave moves around a barrier or through an opening in a barrier, it bends and spreads out.

Question 4: Tsunami

Answer:

Huge surface walls on oceans.

Question 5: Longitudianal Wave

Answer:

Move the medium parallel to the direction in which the waves travel.

Question 6: Constructive Interference

Answer:

The interference that occurs when waves combine to make a wave with a larger amplitude.

Question 7: Energy

Answer:

Is defined as the ability to do work.

Question 8: Node

Answer:

These points of zero amplitude on a standing wave.

Question 9: Rarefaction

Answer:

The parts where the coils are spread out.

Question 10: Compression

Answer:

The parts where the coils are close together.

Question 11: Destructive Interference

Answer:

The interference that occurs when waves combine to make a wave with a smaller amplitude.

Question 12: Wave

Answer:

Is a distance that transfers energy from place to place.

Question 13: P Wave

Answer:

Longitudinal seismic waves are known as P Wave.

Question 14: Wavelength

Answer:

The distance between two corresponding parts of a wave.

Question 15: Standing Wave

Answer:

Is a wave that appears to stand in one place, even though it is really two waves interfering as they pass through each other.

Question 16: Medium

Answer:

The material through which a wave travels.

Question 17: Hertz (Hz)

Answer:

Measures frequency in units.

Question 18: Seismograph

Answer:

To detect and measure earthquake waves.

Question 19: Resonance

Answer:

Is an increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency.

Question 20: Trough

Answer:

The low part.

Question 21: Amplitude

Answer:

Is the maximum distance that the particles of the medium carrying the wave move away from their rest positions.

Question 22: Vibration

Answer:

Is a repeated back-and-forth or up-and-down motion.

Question 23: Refraction

Answer:

The bending of waves due to a change in speed.

Question 24: Antinode

Answer:

The points of maximum amplitude on a standing wave.

Question 25: Reflection

Answer:

The interaction with a surface.

Question 26: S Wave

Answer:

Transverse seismic waves are known as S wave.

Question 27: Frequency

Answer:

Is the number of complete waves that pass a given point in a certain amount of time.

Question 28: Mechanical Waves

Answer:

Waves that require a medium through which to travel.
