Light doesn't behave like a wave in Single Slit Interference.
-
True
-
False
Correct Answer
A. FalseExplanation
If it didn't behave like a wave, then you wouldn't see diffraction patterns, therefore it must behave like a wave.Rate this question:

Single Slit interference can occur in a double-slit experiment if the slits are wider than the wavelength of light passing through them.
-
True
-
False
Correct Answer
A. TrueExplanation
Single Slit interference occurs in any slit that is slightly larger than the wavelength of light that passes through it.Rate this question:

A single slit 1.0mm wide is illuminated by 450nm light. What is the central maximum (in cm) width in the diffraction pattern on a screen 5.0m away?
-
3 cm
-
0.8 cm
-
0.45 cm
-
0.5 cm
-
None of the Above
Correct Answer
A. 0.45 cmExplanation
Use the equation with n = 1, λ = 450 * 10^-9m, D = 5.0m and d = 1 * 10^-3m. Find Yn and then multiply it by 2 to get the width of the central max.Rate this question:

The equations for single slit interference are exactly the opposite as those for double-slit interference.
-
True
-
False
Correct Answer
A. TrueExplanation
The equation for nodal lines in double slit is the same as antinodal lines in a single slit and the reverse is true as well.Rate this question:

- 6.
In Single Slit Interference, there can be an infinite number of dark and bright fringes.
-
True
-
False
Correct Answer
A. FalseExplanation
There is always a limited number of dark and bright fringes. This number depends on the maximum value of n which can be calculated by d/λ.Rate this question:

When violet light of wavelength 415nm falls on a single slit, it creates a central diffraction peak that is 9.2 cm wide on a 2.55m away screen. How wide is the slit?
-
3 X 10^-8 meters
-
3.8 X 10^-7 meters
-
2.3 X 10^-7 meters
-
4.2 X 10^-6 meters
-
None of the Above
Correct Answer
A. 2.3 X 10^-7 metersExplanation
Remember to divide the 9.2 cm by 2 because the equations that we know are for the distance from the center for any 1 side. Then use the equation and plug in the known values to find the answer.Rate this question:

When does Single Slit Diffraction Occur?
-
When the Slit Width is smaller than λ
-
When the Slit Width is the same as λ
-
When the Slit Width is slightly larger than λ
-
Both A and B
-
Both B and C
Correct Answer
A. Both B and CExplanation
Single Slit Diffraction occurs when the slit width is slightly greater than or equal to λ. When it is equal to λ, only the central maximum and 2 nodal points are visible, but diffraction still occurs.Rate this question:
