Answer:
Particles vibrate parallel to the direction the sound travels
Answer:
Transverse wave- Back and forth at right angles to the direction of the wave arrow.
longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.
electromagnetic wave- two alternating waves moving at right angles to each other.
Explanation:
In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.
In a transverse wave, the particles vibrate parallel to the wave motion
Electromagnetic waves occur as a result of the interaction between two waves and are normally transverse in nature.
The moon completes its orbit around the Earth in 27.32 days (rounded).
That's NOT the length of the cycle of the moon's phases. The time from
any phase until the next appearance of the same phase is 29.53 days.
