Explain how time of flight is used to measure lattice constants

The lattice constant is actually dimension of unit cells in a crystal lattice. Three dimenions are a, b, and c. in case of cubic constants are equal to a only

generally, ToF is a method used to measure the distance between a sensor and an object (or lattice plane), when signal emmited from sensor reflected by an object based on the time taken by signal. The total time taken from senor to target and target to sensor is time of flight.

so distance is=time of flight/2 * velocity of signal

generally x ray are used for lattice dimension determination with and robust algorithm for higher accuracy.

The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 30.0 cm.

An acceleration voltage of 30.0 kV is used to accelerate ions into the 1.54 m flight tube of a time‑of‑flight (TOF) mass spectrometer. The frequency at which spectra can be recorded is dependent on how long it takes the slowest ion to travel from the source to the detector. If you wish to scan up to ?/?m/z 6801 at what frequency (spectra/s) could spectra be recorded if a new spectrum begins each time the slowest ion reaches the detector? frequency:................spectra/s

Calculate the probability that a flight will depart early or on-time. P(flight early/on time DEPP)=(#flights early/on time)/(total # flights)=363/500= 0.726 Calculate the probability that a flight will arrive late. P(Late ARR)=(#flights late)/(total # flights)=170/500= 0.34 Calculate the probability that a flight departs late or arrives early (does not say on time). P(Late/early DEPP)=(#flights Late+ early)/(total # flights)=428/500= 0.856 If the above is correct, Assume now that the random variable X=Arrival Time is exactly normally distributed with mean m= -2.5 and...
