find the of cycles made in this picture
2 cycles are in this picture
they keep on moving without effecting each other
what is it called when a wave bounces off of an object
reflection
one of the ways we use waves everyday that is everywhere around us
electromagnetic radiation
how do you find wave speed
v=(wave Length) X (frequency)
what is the amplitude of this wave
the amplitude is 1.5m
what is the name of the waves that humans can see
the viable light spectrum
what is it called when a wave changes medium
diffraction
waves that vibrate parallel to the movement
Transverse Wave
how to find the amplitude of a wave
1/2(high point)/(low point)
a wave has a frequency of 50hz and a wave length of .1 meters what is its velocity
its velocity is 5m/s
light
what is it called when a wave bends going into a new medium
refraction
waves that vibrate parallel to the movement
Longitudinal Wave
how do you find the period
period=1/frequency
in 4 seconds the wave oscillates 40 times what is its frequency
frequency is 10hz
what is it called when 2 waves collide and cancel out making it look like a flat line
Destructive Interference
what is it called when a wave is the same as the natural frequency of an object making it oscillate faster
resonance
a mechanical wave that propagates along the interface between differing mediums.
Surface Wave
how do you find the frequency
a wave oscillates 400 times in 50 seconds what is its period
when where waves first radio waves discovered and by who
Heinrich Hertz in the 1880s
what is it called when a wave gets compressed or stretched by a moving object making it change
Doppler effect
what do waves move/ carry
energy
how do you find the wave length
look for 2 points at the same area of the wave and measure the difference / wave length=v*f
