Why would a patient need to consume a barium meal if they were having an x-ray to examine their intestine?
These areas of the body cannot normally be seen on x-ray images unless coated in a white liquid called barium contrast.

When measuring something small, but that repeats many times (such as the wavelength of a water wave), how can you increase the accuracy of your measurement?
Measure multiple and then divide by the number you measured (e.g. measure 10 wavelengths and then divide by 10)
