Diffraction Grating Flashcards
1
Q
What do bright and dark lights correspond to?
A
- Bright light = constructive
- Dark light = destructive
2
Q
What is zero order?
A
- Has the largest brightness
3
Q
Diffraction Grating Equation
A
- dsinθ = nλ
4
Q
dsinθ = nλ
A
- d= distance between slits in the grating
- θ = angle between maximum and zero line
- λ = wavelength of incident light
- n = order of the maximum
5
Q
Slit spacing
A
- A diffraction grating is made of many slits
- 1/x = d
- d = slit spacing
- x = slits per metre
