Key Idea.
Section 1
Wavelength Defines Light Type
What physically makes UV light different from visible light? Light moves as a wave. The physical distance from the peak of one wave to the peak of the next is called the wavelength.
This physical property acts like a fingerprint—each type of light has a unique wavelength. Visible light corresponds to a specific range of wavelengths, while UV light corresponds to a different, shorter range.
Section 2
The Energy-Wavelength Relationship
The wavelength of light determines how much energy it carries. There is a predictable pattern: shorter wavelengths pack more energy into the same space than longer wavelengths.
UV light has a short wavelength, which means it carries high energy capable of breaking chemical bonds (like DNA).
