5392 Led light wavelength measurement kit
The light emitted by a LED, is not monochromatic; it covers a small frequency band. If you want to measure Planck’s constant with a LED , it is necessary to know this band medium frequency, which is easy to measure with this kit that exploits the diffraction grating.
