We've figured out what part of the salt causes the flame to change color, so now let's measure the wavelengths created with four metals.
Use the ruler under the "tools" icon in the upper right of the video player to measure the wavelengths of light released by each compound.
Fill in the table below with the wavelengths emitted in each trial.
Some trials may have lots of background light present, just record the center-point of the bright lines.
