A laser beam is incident on two slits with a separation of 0.200 mm, and a screen is placed 5.00 m from the slits. If the bright interference fringes on the screen are separated by 1.58 cm, what is the wavelength of the laser light? 2. Find the distance between two slits that produces the first minimum for 410-nm violet light at an angle of 45.0. 3. What is the index of refraction of a material for which the wavelength of light is 0.671 times its value in a vacuum? 4. In a Young two-slit experiment, a source of light of unknown wavelength is used to illuminate two very narrow slits that are a distance 0. 120 mm apart. Bright fringes are observed on a screen a distance of 3.60 m from the slits. The separation between the bright fringes is 1.86 cm. 3.60 m a) Explain how the bright fringes are formed. b) Determine the wavelength of light. 5. A riverside warehouse has two open doors, as shown. Its interior is lined with a sound - absorbing material. A boat on the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely Open door - -- 20.0 m audible. The principal wavelength of the sound waves is 3.00 m. Assuming d| |- z- -.. person B is at the position of the first minimum, determine the distance Open door between the doors, center to center. -150 m 6. Two small speakers S are position a distance of 0.75 m from each other, as shown. The two speakers are each emitting a constant 2500 -5.0 m Hz tone, and the sound waves from the speakers are in phase with 0.75 m each other. A student is standing at point P, which is a distance of 5.0 m from the midpoint between the speakers, and hears a maximum as expected. Assume the reflections from nearby objects are negligible. Use 343 m/s for the speed of sound. a) Calculate the wavelength of these sound waves. b) The student moves a distance Y to point Q and notices that the sound intensity has decreased to a minimum. Calculate the shortest distance the student could have moved to hear this minimum c) Identify another location on the line that passes through P and Q where the student could stand in order to observe a minimum. Justify your answer. d) i. How would the answer to b) change if the speakers were moved closer together? ii. How would the answer to b) change if the speakers were moved further apart? 7. A beam of monochromatic light is diffracted by a slit of width 0.600 mm. The diffraction pattern forms on a wall 1.30 m beyond the slit. The width of the central maximum is 2.00 mm. Calculate the wavelength of the light. 8. Calculate the wavelength of light that produces its first minimum at an angle of 36.9 when falling on a single slit of width 1.00 um.
