9.3 Waves Vocab & Comprehension Quiz

What is the definition of wavelength?

• The color of a wave

• Distance between successive crests of a wave

• The speed of a wave

• The temperature of a wave

Define frequency in the context of waves.

• The distance between two peaks of a wave

• Number of complete cycles of a wave that occur in a given time period

• The speed at which a wave travels through a medium

• The amplitude of a wave

What is the amplitude of a wave?

• The number of oscillations per second

• The measure of the maximum disturbance in the medium from its rest position

• The speed of the wave

• The distance between two consecutive crests or troughs

Explain the concept of wave speed.

• The rate at which a wave oscillates

• The amplitude of a wave

• The distance a wave travels in a given amount of time.

• The speed of sound in air

What is the difference between transverse and longitudinal waves?

• Transverse waves move in a straight line, while longitudinal waves move in a zigzag pattern.

• Transverse waves move perpendicular to the direction of the wave, while longitudinal waves move parallel to the direction of the wave.

• Transverse waves cannot travel through solids, while longitudinal waves can only travel through solids.

• Transverse waves move parallel to the direction of the wave, while longitudinal waves move perpendicular to the direction of the wave.

Define reflection of waves.

• The process in which waves disappear after hitting a surface.

• The process in which waves speed up after hitting a surface.

• The process in which waves change color after hitting a surface.

• The process in which waves bounce off a surface and change direction.

What is refraction of waves?

• Change in direction of waves as they pass from one medium to another

• Change in speed of waves as they pass from one medium to another

• Change in frequency of waves as they pass from one medium to another

• Change in amplitude of waves as they pass from one medium to another

Explain the phenomenon of diffraction.

• Diffraction is the reflection of waves off a surface.

• Diffraction is the absorption of waves by a material.

• Diffraction is the amplification of waves as they travel through a medium.

• Diffraction is the bending of waves around obstacles and the spreading of waves as they pass through openings.

What is the relationship between frequency and wavelength?

• Directly related

• No relationship

• Inversely related

• Randomly related

Define the term interference in the context of waves.

• The process of waves canceling each other out

• The process of waves amplifying each other

• The process of waves changing direction

• The phenomenon where two or more waves overlap and combine to form a new wave.
