Question

1) Light from a monochromatic source shines through a double slit onto a screen 5.00 m away. The slits are 0.180 mm apart. The dark fringes on the screen are measured to be 1.70 cm apart. What is the wavelength of the incident light? A) 457 nm B) 306 nm C) 392 nm D) 612 nm E) 784 nm 2) A single slit forms a diffraction pattern, with the first minimum at an angle of 40.0° from central maximum, using monochromatic light of 490-nm wavelength. What is the width of the slit? A) 762 nm B) 731 nm C) 700 nm D) 668 nm E) 637 nm 3) In the figure, a slit 0.30 mm wide is illuminated by light of wavelength 426 nm. A diffraction pattern is seen on a screen 2.8 m from the slit. What is the linear distance on the screen between the first diffraction minima on either side of the central diffraction maximum? Answer:
