Recipe for a Rainbow

Deep Space Diary

Activity 2.3

Webb uses the light collected by its huge primary mirror to help us learn about distant stars. Some of its specialist instruments split the light into spectra, which astronomers use to discover more about objects in space, such as what they are made of. Using prisms, this activity explores how we can split white light into the spectrum to make a rainbow.
