Practice Problems on Single Slit Diffraction
Q1: A single-slit diffraction pattern is formed on a screen 2 meters away. If a light of wavelength 500 nm produces the first minimum at an angle of 30 degrees, what is the width of the slit?
Q2: Light with a wavelength of 600 nm passes through a single slit and produces a diffraction pattern. If the angular width of the central maximum is 20 degrees, calculate the width of the slit.
Q3: In a single-slit diffraction experiment, if the second minimum is observed at an angle of 45 degrees and the wavelength of light used is 450 nm, find the width of the slit.
Q4: A diffraction pattern is observed on a screen placed 1.5 meters away from a single slit. If light of wavelength 700 nm produces the first minimum at an angle of 45 degrees, determine the width of the slit.
Q5: When monochromatic light with a wavelength of 400 nm passes through a single slit, the first minimum is observed at an angle of 15 degrees. What is the width of the slit?
Single Slit Diffraction
Single Slit Diffraction is a fundamental concept in wave optics that explains how light behaves as a wave when passing through a narrow slit. When coherent light (like a laser) goes through a single narrow slit, the waves spread out, and their interaction creates a pattern on a screen placed some distance away. This phenomenon, known as diffraction, leads to the formation of alternating bright and dark regions, showcasing the wave nature of light.
In this article, we’ll learn core concepts, types, and practical applications of Single Slit Diffraction, aiming to simplify and explore its patterns and formulas.
