31 . 2 S I U N I T S O F L E N G T H M A S S A N D T I M E, ,There are ways of describing the physical world that do not involve measure-ment. For instance, we might talk about the color of a flower or a dress. But theperception of color is subjective; it may vary from one person to another. Indeed,many people are color-blind and cannot tell certain colors apart. Light received byour eyes can be described in terms of wavelengths and frequencies. Differentwavelengths are associated with different colors because of the physiologicalresponse of our eyes to light. But unlike the sensations or perceptions of color,wavelengths can be measured. They are the same for everyone. In other words,measurements are objective. Physics attempts to describe and understand nature in anobjective way through measurement.S T A N D A R D U N I T SMeasurements are expressed in terms of unit values, or units. As you are probablyaware, a large variety of units are used to express measured values.Some of the earliest units of measurement, such as th
