7SCI-Q1-T4- Behaviors of Waves

What is a wave?

• A periodic disturbance that transfers energy from place to place.

• A solid object that moves energy through a vacuum.

• A type of electromagnetic radiation.

• A sound that travels through air.

Which type of wave requires a medium to travel through?

• Electromagnetic wave

• Mechanical wave

• Radio wave

• Light wave

What is a vacuum?

• A space filled with air.

• A space completely empty of matter.

• A medium for sound waves.

• A type of mechanical wave.

Which of the following is an example of electromagnetic radiation?

• Ocean waves

• Sound waves

• Radio waves

• Mechanical waves

How do electromagnetic waves differ from mechanical waves?

• Electromagnetic waves require a medium to travel through, while mechanical waves do not.

• Electromagnetic waves transfer energy without a medium, while mechanical waves require a medium.

• Electromagnetic waves are periodic disturbances, while mechanical waves are not.

• Electromagnetic waves cause particles to vibrate, while mechanical waves do not.

What causes particles in a medium to vibrate?

• Electromagnetic radiation

• Periodic disturbances from waves

• Vacuum energy

• Light waves

What is the direction of vibrations in a transverse wave relative to the direction of the wave?

• Parallel to the direction of the wave

• Perpendicular to the direction of the wave

• At an angle of 45 degrees to the direction of the wave

• Opposite to the direction of the wave

What is the maximum distance the medium vibrates from its resting position in a wave called?

• Wavelength

• Crest

• Amplitude

• Trough

Which of the following is an example of a longitudinal wave?

• Water waves

• Electromagnetic waves

• Sound waves

• Light waves

What happens to the air in your throat when your vocal cords vibrate back and forth to produce sound?

• The air remains still

• The air compresses and expands

• The air moves in a circular motion

• The air vibrates perpendicular to the vocal cords
