True or false: Transverse and compressional waves are the two types of mechanical waves.

False. 'Transverse' is OK. But whether you call the other type 'compressional' or 'longitudinal', it's definitely not 'Congressional'.

The two types of mechanical waves are transverse and longitudinal, with the former having a perpendicular disturbance to the direction of propagation and the latter having a parallel disturbance.

The statement regarding mechanical waves is false. Mechanical waves are indeed categorized based on their type of motion, but not as Transverse and Congressional waves. Mechanical waves fall into two categories: transverse waves and longitudinal waves.
A transverse wave propagates so that the direction of the wave's disturbance is perpendicular to the direction of propagation. This is seen in waves on strings and electromagnetic waves like visible light. An example would be waves on the surface of the water where the disturbance moves up and down while the wave travels horizontally.
On the other hand, in a longitudinal wave, the disturbance is parallel to the direction of propagation. These are typically sound waves in air or water, which involve periodic variations in pressure that transmit through fluids. The sizes of disturbances, known as amplitude, in both transverse and longitudinal waves are independent of their speed of propagation.
In summary, the correct pair representing the two types of mechanical waves based on the type of motion are transverse and longitudinal waves.

Transverse and longitudinal waves are the two types of mechanical waves. Transverse waves have disturbances that move perpendicular to the direction of propagation, while longitudinal waves have disturbances that move parallel. Examples include waves on a string for transverse and sound waves for longitudinal.
