Explanation Given info: The wavelength of the helium-neon laser is 633 nm . The distance between the two m = 1 bright fringes is 32 cm . The distance of the screen from the grating is 2.0 m . Expression for constructive interference is, y m = R ( m λ d ) (I) • y m is the position of the m th order maximum. • R is the distance between the slit and the screen. • m is the order of the fringe. ( m = 0 , ± 1 , ± 2 , … ) • λ is the wavelength of the light. • d is the distance between the slits. For first-order bright fringes on both sides of the centre of the screen, m = ± 1 Substitute + 1 for m to find y + 1 . y + 1 = R { ( + 1 ) λ d } = + R ( λ d ) Substitute − 1 for m to find y − 1 . y − 1 = R { ( − 1 ) λ d } = − R ( λ d ) Formula to calculate the distance between the two first-order bright fringes is, Δ y = y + 1 − y − 1 • y + 1 is the position of the first-order bright fringes above the center point on the screen. • y − 1 is the position of the first-order bright fringes below the center point on the screen. Substitute + R ( λ d ) for y + 1 and − R ( λ d ) for y − 1 to find d

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…
