The former is an empirical observation, the latter is simply opinion. Science relies heavily on observation and measurement, and the vast majority of research involves some type of practical experimentation. Thi
What is the principle of a deflection magnetometer? What is redshift? What is a quasar? What is light? What is wavelet? what is the Doppler effect? Explain. What is a vibration magnetometer? What is the medium for convection? Identify and describe the steps of the scientific method. ...

LiDAR relies on ahighly directed laser beam. In air-light travels at a practically constant speed of light. This is basically the universal speed limit and clocks in at about 3×108m/s. This can be used to determine the distance of objects in a method called atime of flight (TOF). Whe...
Multiple frequency-shift keying (MFSK) is a method of signal modulation that extends the radio teletype (RTTY) two-tone technique to multiple tones, producing fewer errors. MFSK signal modulation technique involves discrete audio tone bursts of different frequencies, which deliver digital data. This ...
what is the Doppler effect? Explain. What is pulsed laser deposition? What are its applications? What are optical instruments? What are molecular vibrations? What is the principle of a deflection magnetometer? What is sonar method? What is luminous intensity?
OFDM systems must have closely tuned transmitters and receivers. This requires the timing on signal modulators and demodulators be closely matched and produced to tight tolerances. It also makes the system more sensitive to Doppler shift and, therefore, less effective for high-speed moving vehicles....

The further away something is, the further back in time you are looking. As the universe is expanding, the light from these distant objects is stretched into longer wavelengths. This is known as the redshift, and it is the light equivalent of the Doppler effect that you can hear when vehi...
the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are stretched out, orredshifted. Known as the Doppler Effect, the same phenomena occurs with waves of light at all ...
