Hi, I need a software or an apparatus (available in school conditions) to measure wavelengths of visible light. In my lab I use coloured filters to get different colours of light, but I have to measure exact wavelengths.
Thank you in advance

Answer:

The wavelength may be measured by Diffraction grating experiment, Newton’s rings experiment etc.
