SPS9 - Properties of Waves

What is a Mechanical Wave?

• A type of energy that moves through a vacuum

• A wave that transmits energy through a medium

• A wave that exists only in mechanical systems

• A wave that can travel without a medium

How are particles of a medium displaced in a Longitudinal Wave?

• In a direction perpendicular to the energy movement

• Randomly

• In a direction parallel to the energy movement

• Not displaced at all

What describes the displacement of particles in a Transverse Wave?

• Particles move in a direction parallel to the direction of energy

• Particles are not displaced

• Particles move in a direction perpendicular to the direction of energy movement

• Particles vibrate but stay in the same place

What does the term 'Frequency' refer to in wave terminology?

• The height of the wave

• The speed of the wave

• How often the wave occurs

• The energy of the wave

What is the Amplitude of a wave?

• The speed of the wave

• The pitch of the sound

• The height of the wave

• The frequency of the wave

What does 'Pitch' describe in terms of sound?

• The loudness of the sound

• The duration of the sound

• How high or low a sound is

• The speed of sound waves

What do waves primarily transport?

• Matter

• Energy

• Light

• Heat

What is required for mechanical waves to travel?

• Vacuum

• Medium (solid, liquid, gas)

• Electricity

• High temperature

Can electromagnetic (EM) waves travel through empty space?

• No, they require a medium

• Yes, and they can also travel through a medium

• No, they only travel through solids

• Yes, but only through liquids and gases

What determines the speed of mechanical waves?

• The source of the wave

• The distance it travels

• The medium through which it travels

• The amplitude of the wave
