1. A transverse wave has regions of compression and rarefaction.
2. A mechanical wave needs a medium for it to propagate.
3. A longitudinal wave is produced when the partides in a medium move parallel to the direction of wave motion.
4. Water wave is an example of an electromagnetic wave.
5. Sound waves can travel in a vacuum.

Answer:
True
True
False
False
False
Explanation:
True - This statement is correct. A transverse wave is a type of wave where the particles of the medium oscillate perpendicular to the direction of wave motion. The regions where the particles are closer together are called compressions, while the regions where the particles are farther apart are called rarefactions.
True - This statement is correct. A mechanical wave is a type of wave that requires a medium for it to travel. Examples of mechanical waves include sound waves, water waves, and seismic waves.
False - This statement is incorrect. A longitudinal wave is a type of wave where the particles of the medium oscillate parallel to the direction of wave motion. An example of a longitudinal wave is a sound wave.
False - This statement is incorrect. Water wave is an example of a mechanical wave, not an electromagnetic wave. Electromagnetic waves include visible light, radio waves, microwaves, X-rays, and gamma rays.
False - This statement is incorrect. Sound waves cannot travel in a vacuum since they require a medium to propagate. This is because sound waves are a type of mechanical wave. Electromagnetic waves, on the other hand, can travel in a vacuum since they do not require a medium for their propagation.
