Longitudinal waves:

• All travel at the same speed
• Are caused by vibrations that are parallel to the direction of wave travel
• Are caused by vibrations that are perpendicular to the direction of wave travel

Transverse waves:

• All travel at the same speed
• Are caused by vibrations that are parallel to the direction of wave travel
• Are caused by vibrations that are perpendicular to the direction of wave travel

Waves:

• Transfer energy and matter
• Transfer energy without transferring matter
• All travel at the same speed

Which is the correct equation for wave speed?

• v = f / λ
• v = f x λ
• v = f² x λ
• v = f x λ²

Which is the correct equation for the frequency of a wave?

• f = 1 / T
• f = λ / T
• f = λ x T
