4) Interference and Diffraction Phenomena (10 points) (a) In a single slit diffraction experiment with a screen far away from the slit, with waves of wavelength 1, there will be no intensity minima if the slit becomes too small compared to the wavelength. What is the minimum slit width (in terms of ) for which no intensity minimum occurs? (Note: if there is no minimum, the screen looks essentially fully illuminated. Think what condition that puts on the angle of...

Part I
Physics 8B Lab 8-Diffraction rev 4.0 Part I: Single-Slit Diffraction Here light shines on a single narrow slit of width a. The name may suggest only one wave passes through the slit, but that is misleading. The slit will be treated not as a single point source, but rather as having some finite size. So what you are studying is the interaction between all the waves that pass through this narrow opening. They will result in a diffraction...

In an experiment to investigate the diffraction of light by a single slit, a narrow parallel beam of light is passed through a narrow slit before it falls on a screen some distance away. Which ofthe following statements is/are correct? 1. If the slit width is reduced, the total light energy falling on the screen is decreased, but the width of the central diffraction band will be increased. 2. If the light source is replaced by one producing light of...

Experiment 3 1. Student passes 633 nm laser light through a narrow slit and observe the diffraction pattern on a screen 7.00 m away. The distance on the screen between the centers of the first minima on either side of the central bright fringe is 35.0 mm. (a) How wide is the slit? (b) The intensity at the center of the pattern is lo. What is the intensity at a point on the screen 3.80 mm from the center of...

1. A single slit forms a diffraction pattern, with the second minimum at an angle of 40.0° from central maximum, when monochromatic light of wavelength 630 nm is used. What is the width of the single slit? 2. Consider a two-slit experiment in which the slit separation is 3.0 × 10-5 m and the interference pattern is observed on a screen that is 2.00 m away from the slits. The wavelength of light passing through the slits is 420 nm....

1) In a double slit experiment, what happens to the fringe pattern when the slit separation (d) is decreased and the screen is moved away from the slit ( L is increased)? a) fringes get further apart b) fringes get closer together c) cannot be determined without knowing the values of d and L 2) White light is being analyzed by a diffraction grating (100 lines/mm). In the interference pattern, the third order blue (wavelength=400 nm) appears 10 cm from...

Question 8 You are conducting an experiment on the diffraction of light through a single narrow slit. You have situated your viewing screen a distance of 1 m away from the slit, with blue light of 450 nm and the slit width is 2.4um. You observe a normal interference pattern with a bright central maximum. What happens to the central maximum if you switch out the 2.4um single slit for a 4.8um single slit? No change occurs to the central...
