Question 1. Find the first few maxima and minima for the diffraction pattern of two slits separated by 12 μm with a screen 50 cm away assuming we use a laser with a wavelength in air of 550 nm.

Question 2. Using these values sketch a graph of light intensity versus distance from the central maximum (y = 0).

Question 3. If you then examine two slits separated by 1.2 μm what wavelength light should you use to keep the pattern unchanged assuming the screen is still at 50 cm.

Question 4. Review why single slit diffraction occurs and make sure you are clear on the differences and similarities between the equations for single slit maxima and minima and double slit maxima and minima (they look really really similar but there are subtle differences).

1. A single slit produces a diffraction pattern on a distant screen. Show that the separation distance between the two minima on either side of the central maximum is twice as large as the separation distance between all the other neighbouring minima. Compare your result to the corresponding case for a double-slit pattern with very narrow slits.

2-) A diffraction/interference pattern using a red helium-neon laser as a light source is observed on a screen a distance of 1.20 m from the element(s) producing the pattern. Using positive values to indicate distances to the right of the center of the pattern on the observing screen and negative values for distances to the left of the center, the following data is taken : Maxima(Cm) Minima(cm) -6.60 -6.10 -5.40 -4.75 -4.30 -3.60 -3.00 -2.35 -1.80 -1.20 +1.70 +1.15 +3.00...

Find the wavelength of the laser through two slits. The distance between the slit to the screen is 1 meter, the two slits are separated by 0.01 mm, and the distance between interference maxima is 6.33 cm. The angle is also 3.63 degrees between the first maxima (center) and the second maxima, with an order of m =1. What color laser is this, and does your answer match up with the wavelength of a HeNe laser?

When you look at a single slit diffraction pattern produced on a screen by light of a single wavelength, you see a bright central maximum and a number of maxima on either side, their intensity decreasing with distance from the central maximum. If the frequency of the light is increased, A the pattern shrinks in size. (central maximum less wide; other maxima in closer to it) B it does not affect the size of the pattern. C the width of...

With a monochromatic light of wavelength ?? = 532 nm A double-slit interference pattern is produced on a screen as shown in the picture. The slit separation ?? is 0.10 mm, and the slit–screen separation ?? is 50 cm. Assume that the angle θ (from the slit center to the maxima and minima) small enough to permit use of the approximations sin θ ≈ tan θ ≈ θ, in which θ is expressed in radian measure. a. A strip of...

1) A two slit interference/diffraction pattern is set up (thus for this problem we will take into account the effects of both diffraction and interference). You are given that the screen is 1.8 m away from the slits with width .01 mm and spacing .05 mm and light of wavelength 640 nm is used. What is the smallest order interference maximum that is \"missing\" from the interference/diffraction pattern on the screen? n=

Coherent light of wavelength 780 nm falls on a rectangular slit of width (horizontal) 3.00 micrometer by 1.50 micrometer (vertical). The resulting diffraction pattern is projected on a screen 75.0 cm from the rectangle.
