If sound travels on average 342 m/s, find the following. (a) What is the angle of the first order maximum? 0 H (b) Find the slit separation when you replace the sound wave with a 3.50 cm microwave, and the angle of the first order maximum remains unchanged. m U (c) If the slit separation is 1.00 pm, what frequency of light gives the same rst order maximum angle?
