Explanation Draw the function ϕ = π a sin θ λ by using figure 38.7 as a starting point. Write the condition for first order central maxima in diffraction. a sin θ = λ Here, a is the slit width, θ is the angle of diffraction, and λ is the wavelength. Write the condition for second order maxima in diffraction. a sin θ = 2 λ The minima occurs on both sides of central maxima in the above situations. Write the condition for diffraction minima. ( π a sin θ ) / λ = π , − π , 2 π , − 2 π , ... Write the relation between a and the distance between slits. d = 3 a Here, d is the distance between the slits. The interference pattern is observed within the diffraction envelope. Write the condition for the interference maxima observed within diffraction pattern. d sin θ = m λ Here, m is the order of diffraction. Rewrite the above equation by substituting 3 a for d . 3 a sin θ = m λ a sin θ λ = m 3 Multiply on both sides with π

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will p…

Students have asked these similar questions

You illuminate a slit with a width of 78.1 µm with a light of wavelength 729 nm and observe the resulting diffraction pattern on a screen that is situated 2.27 m from the slit. What is the width w, in centimeters, of the pattern's central maximum? W = cm

Monochromatic light from a laser is incident on a slit 0.38 mm wide. On a screen 2.33 m away from the slit, the distance between the first minima on either side of the central maximum is 2.62 mm. Determine the wavelength of light emitted by the laser. Answer in units nm.

Your research supervisor has given you an opaque foil in which there are two slits separated by 30.0 µm and a helium-neon laser, which emits light of wavelength 632.8 nm. Each of the slits in the foil has a width of 2.00 µm. What is the ratio of the intensity of the n=15 maximum to that of the central maximum? Explain how you came to your conclusion.
