Ranking Task – 2 Slit Interference Clicker Activities

A student will shine red coherent light on a series of double slits with different spacing. The spacing will be about 1000 nm, 2000 nm, 3000 nm, and 4000 nm

Let S1 be the distance between bright spots when the slit spacing is 1000 nm, S2 be the spacing when the slit spacing is 2000 nm, and so on.

Answer the following on your own

Rank the distance between the bright spots on the interference pattern S1>S2>S3>S4 S4>S3>S2>S1 The distances will all be the same Cannot be determined 1 2 3 4 5

Consult with your neighbor and answer again

Rank the distance between the bright spots on the interference pattern S1>S2>S3>S4 S4>S3>S2>S1 The distances will all be the same Cannot be determined 1 2 3 4 5
