A spectrophotometer is a device used for measuring wavelengths in spectroscopy. It measures the intensity of light at different wavelengths, allowing for the analysis of the absorption, transmission, or emission of a sample. Spectrophotometers are commonly used in chemistry, biology, and physics laboratories for various analytical purposes.

Long wavelengths are associated with low frequencies. Examples include radio waves and AM radio signals, which have wavelengths in the range of kilometers to meters.
Radiators and condensers.

Short wavelengths.
relatively short wavelengths compared to higher pitched notes
The process of measuring wavelengths of light is conducted using a spectrophotometer, which separates light into its different wavelengths and measures the intensity of each wavelength. This device can provide detailed information about the properties of light, such as its color and energy levels.
