Question 1.
What happens to the interference pattern when the light source is not coherent?
Show hintHide hint
Think about the phase relationship.
Question 2.
Define fringe width.
Show hintHide hint
It relates to how spread out the patterns appear.
3Question 3.
What is the condition for constructive interference?
- Paths are equal
- Paths differ by half a wavelength
- Paths differ by a full wavelength
Show hintHide hint
Consider the relationship between wave phases.
4Question 4.
True or False: The fringe width is directly proportional to the wavelength.
- True
- False
Show hintHide hint
Think about how changing λ affects β.
Question 5.
In an experiment, if the distance between slits is halved while keeping the distance to the screen the same, how will the fringe width change?
Show hintHide hint
Think about how changes in d modify fringe spacing.
Question 6.
If the wavelength of light is increased while keeping D and d constant, what happens to the interference pattern?
Show hintHide hint
Consider the relationship between wavelength and fringe width.
