A pinhole camera has a small circular aperture of diameter D. Light from distant objects passes through the aperture into an otherwise dark box, falling on a screen at the other end of the box. The aperture in a pinhole camera has diameter D = 0.600 mm. Two point
sources of light of wavelength 500 nm are at a distance L from the hole. The separation between the sources is 2.70 cm, and they are just resolved by the camera. What is L?

One of the round faces of a solid 3.25 m cylindrical plastic tube is covered with a thin black coating that completely blocks light. The opposite side is covered in a fluorescent coating that glows when light hits it. In the center of the black face, two parallel, straight and thin slits are made, 0.225 mm apart. When laser light with a wavelength of 632.8 nm and perpendicular to the black face passes through these slits, it is observed that the central bright band on the opposite face is 5.82 mm wide, measured between the dark bands that limit it to each side,
What is the index of refraction of the plastic?
A green laser beam with a wavelength 500 nm passes through a partially reflecting Pyrex plate that transmits 50% of the incident light. The output surface of that plate is d0 =1.6 cm from a screen. A d1 = 8.0 mm thick glass plate that has an index of refraction n = 1.50 is inserted into that 1.6 cm gap . With that glass plate partially filling the gap, how many wavelengths of the light are there between the output surface of the Pyrex plate and the screen?

- In one arm of a Michelson interferometer is a transparent container initially full of air, with internal length 6.76 cm in the beam direction. The container is slowly filled with a liquid, and you notice 105986 bright fringes on the photodiode at the interferometer output. If you are using laser light with wavelength 554 nm, what is the refractive index of the liquid? The refractive index of air at this wavelength can be taken as 1.0003. [Aside: you would need to have a slight tilt in the laser beam relative to the liquid surface, but this does not affect your result. ]arrow_forwardA light with a wavelength of 500 nm (red color) travels from a laser to a photocell in 15 ns. When a thin glass slab is placed normally in front of the photocell it takes the light 18 ns to travel from the laser to the photocell? When the Laser beam passes through the glass slab it changes to blue in color (λ = 660 nm). What is the thickness of the glass slab?arrow_forwardLight of wavelength λ = 580 nm is incident upon two thin slits that are separated by a distance d = 25 μm.
