In a double slit interference measurement,the 2nd diffraction minimum coincides with the m=9 interference maximum. Light 530nm in wavelength is used, and the distance between the slits and the screen in 1.1m, the slit width is 4μm. (a) How many full interference bright fringes can you see within the main diffraction envelope. (b) Find the slit separation? (c) What is the inter-fringe distance? (d) One of the slits is covered with a thin piece of transparent materia lof index of refraction n=1.1 and thickness of 2.1μm, how far above the main axis is the central maximum

In a double slit interference measurement, 6 full bright fringes are inside the second secondary diffraction peak. The bright fringes are completely covered by diffraction minima. The slit separation is 20 micrometers. The distance between the slits and the screen is 1.3m. Laser of wavelength 532 nm is used. a) How many full interference bright fringes can you see within the central diffraction peak? b) What interference maximum coincides with the 4th diffraction minimum? c) Find the distance on the...

Light of unknown wavelength passes through a double slit, yielding both double slit and diffraction patterns on a screen that is 1 m away from the slits. You see that the 9th double-slit maximum coincides with the 2nd single-slit diffraction minimum. You also observe that the first diffraction minimum is located 3 cm from the central axis on the screen. (a) What is the ratio of double-slit separation to single slit width, d/a? (b) If d = 72 µm, what...

If you were shown three different interference patterns (double slit, single slit, and diffraction grating), how could you tell the difference between them? Newton thought that light wasn't a wave because he couldn't see diffraction or interference. Imagine you are transported back in time to convince him otherwise. Write a 1-2 paragraph explanation for Newton explaining why he does not see these features despite the wave nature of light.

In a double-slit interference experiment you are asked to use laser light of different wavelengths and determine the separation between adjacent maxima. You observe that this separation is greatest when you illuminate the double slit with In a double-slit interference experiment you are asked to use laser light of different wavelengths and determine the separation between adjacent maxima. You observe that this separation is greatest when you illuminate the double slit with: 1. yellow light. 2. red light. 3. blue...

The figure (Intro 1 figure) shows the interference pattern obtained in a double-slit experiment with light of wavelength λ. Part A Identify the fringe or fringes that result from the interference of two waves whose phases differ by exactly 2λ. Enter the letter(s) indicating the fringe(s) in alphabetical order. For example, if you think that fringes A and C are both correct, enter AC. Part B The same double-slit experiment is then immersed in water (with an index of refraction of...

What is the condition for light in order to make interference pattern from Young-double slit? How do you make single source to make a source for young double-slit experiment? What happen if you use electron instead of light, what pattern you expect to see, and why? What are the parameters that can affect the interference pattern (mention at least 3)
