Answer 10

Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier wave. The simplest FSK is binary FSK (BFSK). BFSK uses a pair of discrete frequencies to transmit binary (0s and 1s) information.

I got this info from Google For Frequency shift

Answer 11

the displacement of the spectrum to shorter wavelengths in the light coming from distant celestial objects moving toward the observer.

Info from the same place for blue shift

Answer 12

the displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.

Info is from the same place for red shift

Answer 13

wait so, what is frequency shift

Answer 14

@MikeyMaximum please answer!

Answer 15

Look at the first 1 :)

Answer 16

but can you explain it in 7th grade words :)
