definitions
What's the definition of amplitude?
wave length
What is the difference between 2 crests?
wave length
needs a medium
mechanical wave
Once the wave has moved, the
disturbance is
gone
Mechanical Waves
can be either
transverse or Longitudinal
whats the definition of medium?
what is the difference between a transverse wave and a mechanical wave
a transverse wave has particles that vibrate up and down motion and mechanical waves need a medium to travel through
does not need a medium
electromagnetic wave
Frequency =
the number
of waves that pass by a
point each second
Electromagnetic Waves
are ALWAYS
transverse waves.
whats the definition of frequency?
The number of waves that pass a point each second
what is the difference between a wavelength and a amplitude
amplitude is a wave height and a wave length is the distance between one point of a wave to the next identical point
wave bounces after hitting a barrier
reflection
Wave Speed =
speed at which waves
travel through a medium
Amplitude =
= wave height
what needs a medium to travel through (longitudinal or transverse)
mechanical wave
difference between a mechanical and a electromagnet wave
a electromagnet does not need a medium and mechanical needs a medium
The bending of waves
around a barrier or
through an opening is
known as
diffraction
Longitudinal Waves:
waves in which the particles
vibrate back and forth in
compressional pulses
larger amplitude =
= more energy Amplitude
when a wave bounces after hitting a barrier
reflection
whats the differences of refraction and diffraction?
Refraction is the bending of a wave when it passes from one medium to another, changing its speed and direction. Diffraction is the bending and spreading of waves as they encounter an obstacle or opening.
happens when waves overlap
interference
A wave is
a disturbance that
transfers energy
through matter or
space.
Wavelength =
distance between 2 crests or troughs
Wavelength
