Wavelength (Colours) and line spectra.

Click For Summary
SUMMARY

The discussion focuses on the relationship between wavelength and line spectra, specifically comparing green light (510 nm) and red light (650 nm). The experiment involved observing line spacing through slits configured as 2, 2, 6, which indicates the number of slits and their dimensions. It was concluded that the greater spacing of green light lines compared to red light lines indicates a shorter wavelength for green light. This observation highlights the direct correlation between wavelength and the spacing of spectral lines.

1. How does wavelength affect line spectra (the spacing)?

I did some research and found the wavelength of green light to be 510 nm and red light to be 650 nm. So for the experiment I looked through slits (such as 2, 2, 6 (which represents 2 slits, 2 points wide, and separated by 6 points) where 1 point is 0.000352777 metres) )such and observed green light on top and red light on the bottom and compared the lines. I noticed that green light lines were further apart than red light lines. What does this tell me about their wavelengths? THanks

I don't really understand your experiment, but it could be that it is because your eyes can't see red very well.
