what are sparks created by an incomplete path of electric energy?
Arc
what type of wave has the longest wavelenghth?
radio waves
what is the lowest point on a wave?
trough
what is a microwave?
an oven that uses a bunch of electromagnetic radiation to cook things
Why do we no longer see phones with antennas on top of them?
antenna technology has advanced especially in the packing part so we can thread them into smaller places
what is the lowest point on a wave?
trough
what is the shortest wavelenghth?
gamma rays
what is the highest point on a wave?
crest
what is a magnetron?
it generates microwave radiation
How does longer and shorter wavelengths affect the receiving part of information?
Older communication technology used radio waves and required longer antennas and the smaller antennas used the smaller antennas
what is the highest point on a wave?
Crest
what waves can humans see?
visible light
what is wave speed?
wavelength times frequency
operating the oven with no food or food that is extremely low in moisture can cause fire, charring, or arcing
What causes them to change the flow in the transmission antenna very rapidly?
because these towers and our cell phones use digital communication methods
what is a pulling force?
Tension
what waves occur in the sun?
ultraviolet
what is wavelength?
distance from a single point on a wave to an identical point
Can you operate a microwave with the door open?
No doing this can result in harmful levels of exposure to microwave electromagnetic radiation
What allows for packing antennas into smaller places?
antenna technology
what is time needed to complete one wave cycle?
Period
what waves can penetrate most matter?
x-rays
what is frequency?
number of waves produce within a time frame
What do you do if you see arcing in the microwave oven?
you turn off the microwave oven and correct the problem
What can interact with many more types of smaller structures in the place between the transmission and reciever antennas?
wavelength
