A double slit is illuminated head on by laser light with wave length of 500nm. Interference fringes are visible on a screen 5m away, with the fringes closest to the central fringe a distance of 4cm apart. (a) (3) How far are the two slits from each other (what is d in the figure)? (b) (3) The laser light is actually arriving from a spaceship, that was initially at rest. It then accelerates to 0.05 of the speed of light moving away from the slit. What would be the new distance between the closest to center fringes? (c) (2) The laser from the ship has power of 10W such that it could be seen from a large distance. What is the force that the laser device is experiencing due to the light it emits? Assume the laser is a straight beam with all light moving in the same direction as in the figure. (d) (2) The spot size of the laser as it leaves the ship has radius of 0.2m. Estimate the amplitudes of the electric and magnetic fields in the beam of light. Hint first calculate the intensity (power per area) of the beam. \f
