Why would a baseball player see a baseball flying through the air before hearing the ball's crack​ on the bat?

• because sound travels faster through air than light

• because sound travels slower through air than light

• because light and sound travel at the same speed through air

• because light and sound must travel through matter to be seen

How do particles move in a longitudinal wave?

• The vibrations move perpendicular to the wave's direction of travel.

• The vibrations move in opposition to the wave's direction of travel

• The vibrations move in circles along the wave's direction of travel.

• The vibrations move parallel to the wave's direction of travel.

How do electromagnetic and mechanical waves compare?

• Mechanical waves can only travel through a vacuum, but electromagnetic waves can travel through a solid, liquid, or gas.

• Mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a gas.

• Mechanical waves can only travel through a solid, liquid, or gas, but electromagnetic waves can travel through a vacuum.

• Mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a solid.
