First Page:: Wavelengths of Light In Angstroms 1.  My wavelength value is...    __________ Angstroms. 2.  This is the wavelength range for  ______________________. (which type of light?)

Explore the range of the wavelengths
3.  Use this form to record  wavelength values.  See if you can get an idea of the range of
wavelength values for each type of light.  Use the TOOL at the bottom of the page to test
various wavelengths.  Can you determine the boundary numbers which are typically used to
separate each wavelength type from the ones next to it?   Record the numbers here.
Click on 'Gallery' for each wavelength to find out what we can see.
