Hello everyone I couldn't figure it out a simple way to solve 15. 11 C . Please help ! Very appreciated!
Mechanical waves are disturbances that travel through a medium, such as air or water, and transfer energy from one place to another.
There are two main types of mechanical waves: transverse waves and longitudinal waves. Transverse waves have vibrations perpendicular to the direction of wave propagation, while longitudinal waves have vibrations parallel to the direction of wave propagation.
Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum. Additionally, mechanical waves transfer energy through the motion of particles, while electromagnetic waves transfer energy through the oscillation of electric and magnetic fields.
The speed of mechanical waves depends on the properties of the medium they are traveling through, such as density, elasticity, and temperature. For example, sound travels faster in denser mediums and slower in colder temperatures.
Mechanical waves have many practical applications, such as in communication (e.g. sound waves in phones), transportation (e.g. ocean waves for shipping), and imaging (e.g. ultrasound waves in medical imaging).
