Electromagnetic spectrum
The two perpendicular fields in an EM wave.
What are the ELECTRIC field and the MAGNETIC field?
The functions that describe wave behaviour.
What is SINE (and COSINE) function?
300 000 000 m/s
What is the SPEED OF LIGHT (or EM WAVE)?
Values or measurements collected WITHOUT interpretation.
What is DATA?
23071981
What is JOSEF’S BIRTH DAY?
The wave property used to arrange the EM spectrum.
What is FREQUENCY (or WAVELENGTH)?
The property of a wave that determines how strong or intense it is.
What is AMPLITUDE?
The bending of electromagnetic waves as they pass from one medium to another.
What is REFRACTION?
The unwanted random signal present in all systems.
What is NOISE?
The number of push-ups Michal can do.
How much is ALL of them?
The type of radiation that can transfer heat.
What is INFRARED (IR)?
The effect that occurs when two waves meet and CANCEL each other.
What is DESTRUCTIVE INTERFERENCE?
The effect that makes the signal WEAKER the farther it travels.
What is ATTENUATION?
The method that keeps information secret from unauthorized users.
What is ENCRYPTION?
When you get a new satellite TV ANTENNA.
What is ANTENNA GAIN?
According to IEEE, the range of frequencies that cover 8-12 GHz.
What is X-BAND?
The wave property that describes the relative position within one oscillation cycle (or how two waves are delayed to each other).
What is PHASE (or PHASE SHIFT)?
All waves with electric fields aligned vertically.
What is VERTICAL POLARIZATION?
The rate (speed) of taking measurements of the amplitude of a wave.
What is SAMPLING?
The situation when you work faster (or slower) than your colleague during a SHIFT.
What is a DOPPLER SHIFT?
The seven regions of EM radiation, from lowest to highest frequency.
What is RF, MW, IR, VISIBLE LIGHT, UV, X-RAY, GAMMA RAY?
The phenomenon that occurs when two or more waves add together at the same point.
What is the SUPERPOSITION PRINCIPLE?
The propagation effect that causes the signal to arrive at the receiver in different times.
What is MULTIPATH PROPAGATION?
The two DIFFERENT perspectives through which we can look at the SAME signal.
What is TIME and FREQUENCY domain?
The situation when there are commercials on TV, radio, internet, newspapers and billboards that are promoting the sales of WAVES.
What is WAVE PROPAGATION?
