Question 13 1 pts In a doubleslit experiment, Jack obtained the following results: 1. width of 10 fringes is 1.5 cm 2. separation of slits is 1.0 mm 3. slittoscreen distance is 2.40 m What is the wavelength of the light? .. 6.3 x 107 m .. 5.3 x 107 m .. 6.3 x 107 cm .. 6.3 x 107 mm .. 5.3 x 107 mm Question 14 1 pts A drone ies towards Mike at constant speed, and then away from him with constant acceleration, as shown in the diagram. The drone is producing a constant frequency of 185 Hz. Assume the speed of sound in air is 330 m/s. Calculate the speed of the drone when the sound waves being produced behind it have a wavelength of 2 m. Give your answer to 0 decimal places. Constant acceleration x Constant speed . Mike
