5. Blue (450 nm) light is shone through a double slit and forms a diffraction pattern on a screen. If the distance between the double slits is 4.3 pm, calculate the theoretical maximal number of the bright fringes on the screen. (1) 6. Green (550 nm) light is diffracted through a single slit and forms a diffraction patter. The angle of the second dark fringe is 11.2 degree and the screen is placed 90 cm away. Calculate the width of the central bright fringe. (1) 7. Using 650 nm as the wavelength of the light, and 1.2 mm as the diameter of the camera lens. If two apples placed 70 m away from the camera and the camera is just able to resolve them, calculate the distance between the two apples. (1) 8. A tauon has rest energy 1.777 X 109 8V and is moving at a speed of 0.950 relative to the laboratory. (a) In electronvolt (8V), calculate the kinetic energy of tauon. (1) (b) An observer in laboratory measures a distance of 1.2 X 104 m trav eled by this tauon, calculate the proper length and the proper time interval of this movement. (2)
