What is reflection in terms of waves?

• A change in wave direction

• The separation of the coils in a longitudinal wave

• A sound that is repeated because waves are reflected

• Related to air compressions that collide with the eardrum and make it vibrate

• The separation of the coils in a longitudinal wave

• A change in wave direction

• A sound that is repeated because waves are reflected

• Related to air compressions that collide with the eardrum and make it vibrate

• A sound that is repeated because waves are reflected

• A change in wave direction

• The separation of the coils in a longitudinal wave

• Related to air compressions that collide with the eardrum and make it vibrate

What is intensity in terms of sound?

• Related to air compressions that collide with the eardrum and make it vibrate

• A change in wave direction

• The separation of the coils in a longitudinal wave

• A sound that is repeated because waves are reflected

What is compression in a longitudinal wave?

• The closing of the coils in a longitudinal wave

• The separation of the coils in a longitudinal wave

• A change in wave direction

• Related to air compressions that collide with the eardrum and make it vibrate

What determines tone in sound?

• Wave frequency

• Wave speed

• Intensity

• Compression
