By examining a wave’s pattern after it interacts with a barrier or gap, measurements can be made to better understand certain wave phenomena. What is a broad question you can answer by doing this experiment?

Explanation :

When a ray of light passes through the narrow opening then the light diffracts. The process is known as the diffraction of light.

By examining a wave's pattern after it interacts with a barrier or gap, measurements can be made to better understand diffraction wave phenomena.

After diffracting the light forms a pattern consisting of dark and bright bands.

Hence, the question could be " How diffraction of wave occurs? Explain ".

the answer to this is proletariats.

hope this : )
