4 - Wave Optics Flashcards
1
Q
What type of wave can diffract?
A
Any type of wave can diffract, including sound and light waves.
2
Q
For double-slit, what is the intensity like at the brightest spots?
A
The intensity at the brightest spots is 4 times the intensity from one slit.
3
Q
For single-slit, what is the maximum possible intensity behind the barrier?
A
I0
4
Q
What is Rayleigh’s criterion?
A
Rayleigh’s criterion = two objects can be resolved if viewed through a circular aperture if their angular separation in space is greater than or equal to θ1.
5
Q
What does Rayleigh’s criterion imply when the diameter D of the aperture is increased?
A
the greater its resolving power
