Waves are a regular pattern of disturbance that transfer energy and information from one point without any transfer of matter.
v = f x ?
wave speed = frequency x wavelength
m/s Hz m
A soundwave has a frequency of 168Hz and a wavelength of 2m? 168x2 = 336 m/s.
When waves move through a gap or past an obstacle they spread out from the edges - this is diffraction. It is most obvious when
- the size of the gap is similar to the wavelength
- the waves which pass obstacles have long wavelengths
- water waves are…
