Contending Students Task – Dependence of Single Slit Pattern on Slit Width

A student shines red, coherent light on a small single slit A student shines red, coherent light on a small single slit. The student will then increase the width of the opening. Three other students make a prediction about the experiment before it is conducted.

Student A: “The pattern will be unchanged Student A: “The pattern will be unchanged. Student B: “The width of the pattern will increase.” Student C: “The width of the pattern will decrease.”

Answer the following on your own

With which student do you agree? B C I don’t agree with any of them 1 2 3 4 5

Consult with your neighbors and answer again
