Question

1. Set frequency of wave generator to 5Hz.

2. Set amplitude of wave generator to 1cm.
3. Place the barriers 10cm from the wave generator.
4.
5. Sketch the diffraction pattern observed.

What should be step 4?

Answer 1

Separate the barriers so they have a 2cm gap between them.

Step-by-step explanation:

Changing the spacing between the barriers will alter the diffraction pattern.

Answer 2

Separate the barriers so they have a 2cm gap between them.
