Science Flashcards
What is a wave ?
A wave is responsible to transfer energy from place to place
What is a medium ?
A medium can be gas liquid or solid
What are waves that require a medium ?
Mechanical waves
What happens when a source of energy causes a medium to vibrate ?
Mechanical waves form together
What are the types of mechanical waves ?
Transverse waves / longitudinal waves / surface waves /
What are transverse waves ?
A wave that vibrates the medium in right angles
What are longitudinal waves
It vibrates the medium in the same direction the wave travels
What are surface waves ?
A wave that travels along the surface that separates the mediums
What is Amplitude ?
How far the medium in the wave moves
What is wavelength ?
Describes the waves length
What is frequency ?
How often it occurs
What is speed ?
How quick the wave moves
How are three properties related ?
In mathematical formula speed=wavelengths frequency
What happens when the speed of a wave in the medium temperature and pressure don’t change ?
The speed stays the same
