- Q1What direction is the air oscillating and what direction is the wave moving?The air is oscillating perpendicular (right/left) to the velocity of the wave (up).The air is oscillating parallel to the velocity of the wave (up)The air is oscillating parallel to the velocity of the wave (right).The air is oscillating perpendicular (up/down) to the velocity of the wave (right)120s112.39.c.7.c
- Q2How are transverse and longitudinal waves different?Longitudinal waves have oscillations perpendicular to wave velocity. Transverse waves have oscillations parallel to the wave velocity.Both waves oscillate and move the same way, but transverse waves don't require a medium.Longitudinal waves have oscillations parallel to wave velocity. Transverse waves have oscillations perpendicular to the wave velocity.They're the same.120s112.39.c.7.c
