When scientists want to measure and study frequencies in the electromagnetic spectrum, they use different tools and methods.

The electromagnetic spectrum includes many types of waves. It starts with radio waves at the low end and goes all the way up to gamma rays at the high end. Each part of this spectrum is important and has its own uses.

Knowing how to measure these frequencies is really important!

Key Techniques for Measurement

1. Spectroscopy:
   • This method breaks light into different colors or wavelengths using tools like prisms or special patterns called diffraction gratings.
   • By looking at the patterns created, including things like wavelength and brightness, scientists can figure out the frequencies of the electromagnetic waves.
