Question

Wavelength of the first line:

Wavelength of the second line

Wavelength of the third line

Wavelength of the fourth line

Once the diffraction grating has been calibrated, we will use it to measure the wavelengths of a light source. The wavelengths are then compared to the wavelengths from known elements to identify the element. Click on the link below to view the spectrum. Only the first order lines and the four most intense (brightest) are shown. (For the lab, many more lines are visible and you will need to measure more than four lines.) Read the angle for each line and then use the equation Wavelength of the first line: Wavelength of the second line Wavelength of the third line Wavelength of the fourth line

Explanation / Answer

I'm sorry. data is insufficent.

no of lines per centi meter on the grating should be given.
