You%20are%20performing%20a%20two-slit%20interference%20experiment,%20and%20you%20increase%20the%20slit%20separation.%20What%20happens%20to%20the%20spacing%20between%20the%20fringes?

1
You are performing a two-slit interference
experiment, and you increase the slit separation.
What happens to the spacing between the fringes?

1. Stays the same
2. Spacing increases
3. Spacing decreases

2
You are performing a two-slit interference
experiment, and you switch the color of light
from blue to red. What happens to the spacing
between the fringes?

1. Stays the same
2. Spacing increases
3. Spacing decreases

3
You are performing a two-slit interference
experiment, by shining white light on the slits.
Consider any side maxima. Is the red or the blue
component of the side maxima closer to the
central maximum?

1. Red is closer
2. Blue is closer
3. Only white light is in each maxima, so you cant
   tell
