In interferometry, what does the term "fringe visibility" describe?

Fringe visibility is like watching TV! It measures how clear and sharp the patterns are. If it's high, we see nice, sharp patterns; if low, they're fuzzy!

What type of error occurs when equipment is improperly calibrated?

Think of calibration like tuning a guitar! If equipment isn't properly tuned, it gives wrong answers consistently. That's systematic error ? wrong every time!

Which type of detector is commonly used in gas chromatography?

This detector is like a superhero sidekick! It finds even tiny bits of substances by noticing when they become ions, or tiny charged particles. It helps figure out what's in the air!

What is the function of a laboratory thermometer's emergent stem?

Thermometers have a special trick! The emergent stem helps adjust for the liquid expanding when heated, so we get the right temperature reading. Like adjusting a recipe for the perfect cake!
