–/2 points Walker4 28.P.004. My Notes | A person driving at  v  =  18  m/s crosses the line connecting two radio transmitters at right angles, as shown in the figure  ( d 1  =  570  m and  d 2  =  190  m). The transmitters emit identical signals in phase with each other, which the driver receives on the car  radio. When the car is at point A the radio picks up a maximum net signal. (a) What is the longest possible wavelength of the radio waves?    m (b) How long after the car passes point A does the radio experience a minimum in the net signal? Assume that the wavelength  has the value found in part (a).    s 2. –/4 points Walker4 28.P.019. My Notes | A two-slit experiment with slits separated by  2.8   10 -4  m produces a second-order maximum at an angle of  0.0870 ° . (a) Find the wavelength of the light used in this experiment.   nm (b) If the slit separation is  increased , but the second-order maximum stays at the same angle, does the wavelength increase,  decrease, or stay the same?  stay the same decrease     increase Explain.  (c) Calculate the wavelength for a slit separation of  7.5   10 -4  m.   nm 3. –/3 points Walker4 28.P.024. My Notes | Suppose the interference pattern shown in the figure is produced by monochromatic light passing through two slits, with a  separation of  155  µm, and onto a screen  1.23  m away. (a) What is the wavelength of light?   nm (b) If the frequency of this light is  decreased , will the bright spots of the pattern move closer together or farther apart?  closer together farther away
