Part 2. Double Slit Interference
In the pictures on the last page, the rays are emitted in all directions from the slits, but let's concentrate on the rays that are emitted in a direction 0 toward a distant screen (0 measured from the normal to the barrie. One of these rays has further to travel to reach the screen, and the path d difference is given by d sin e to screen
a. Predict the brightness on the distant screen if the path difference is exactly one d sin e wavelength (or any integer number of wavelengths)? Explain your reasoning
b. Predict the brightness if the path difference is N2, 3λ/2, or 5A/2, etc.?
Which equation below tells you the angles (0) at which you will see bright spets and which one tells you the angles (0) for dark spots?

1) Two narrow slits are 0.25mm apart. They are illuminated by light from a helium–neon laser with a wavelength of 633nm, and the interference pattern is observed on a screen 49cm from the slits. (a) What is the angle between the zero-order maximum and one of the first-order images? (b) What is the distance between the two first-order images? 2) The m=3 maximum is located 3cm from the m=0 image when monochromatic radiation illuminates a double slit. The screen is...

Below is an image from a double slit experiment obtained by shining a laser through one. I used a He-Ne Laser, wavelength = 632.8 nm, and shined through two slits whose separation distance is d = 0.250 mm. The light was shined upon a sheet of paper taped to the wall and was 10.0 ft 4.00 inches away from the double slit. I circled the bright spots (constructive interference) and identified the central maximum...
