A helium-neon laser (λ = 632.8 nm) is used to calibrate a diffraction grating. If the first-order maximum occurs at 20.6°, what is the spacing between adjacent grooves in the grating? (In this problem, assume that the light is incident normally on the grating.)
Light from a helium-neon laser passes (λ = 633nm) through a circular aperture and is observed on a screen 5.60 m behind the aperture. The width of the central maximum is 1.20 cm. What is the diameter (in mm) of the hole?
Light from a helium-neon laser (λ=633nm) passes through a circular aperture and is observed on a screen 4.0 m behind the aperture. The width of the central maximum is 2.5 cm .What is the diameter (in mm) of the hole?
Monochromatic light from a helium-neon laser of wavelength 632.8 nm is incident normally on a pair of parallel slits separated by 0.25 mm. If the laser is replaced by the microwave transmitter in your experimental setup transmitting 3 cm waves, what slit separation will be needed to maintain the same angle for the first bright fringe? Give the number only with 2 significant digits after the decimal point, assuming units are in meters.
4. Helium-neon laser light (λ = 632.8 nm) is sent though a 3.3 mm wide single slit. A viewing screen is placed a distance L from the single slit. Choose the correct answer On the viewing screen (a) a bright fringe is observe in the center with alternating dark and bright fringes whose intensity decrease from the center to both sides, (b) a bright fringe is observe in the center with alternating dark and bright fringes with the same intensity...
