We have studied diffraction from a single slit, where light is sent through a thin opening. A similar phenomena occurs when light bends around a thin object, like a human hair. Here the width of the hair plays the role of the width of the single slit. Measurements found that when a beam of light of wavelength 632.8 nm was shone on a single strand of hair, the first dark fringes on either side of the central bright spot were 5.22 cm apart. If the screen is 1.25 meters away, how thick was this strand of hair?
A neutron star has a mass of 2.20 × 10^30 kg (about the mass of our sun) and a radius of 5.20 × 10^3 m. Assume an object falls from rest near the surface of such a star. How fast would it be moving after it had fallen a distance of 0.0083 m.
So as to simulate weightlessness for astronauts in training, they are flown in a vertical circle. If the passengers are to experience weightlessness, how fast must an airplane be moving at the top of a vertical circle with a radius of 1545 m.
