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:

Bright spots on the interference pattern are visible because of:
-
Destructive Interference of Light
-
Constructive Interference of Light
-
Polarization of Light
-
Light is always bright
-
Your eyes are playing games with you!
Correct Answer
A. Constructive Interference of LightExplanation
Constructive interference means that the troughs and crests are lined up which means that the amplitude of the wave is increased and therefore there are bright spots.Rate this question:

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:

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:

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:

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:
-
- 9.
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:
