They have the same frequency. They have the same frequency and they are in phase. Question 3 (1 point) Which of the following might be a valid conclusion for the Young's double-slit experiment? Light travels in a straight line. Light is an electromechanical wave. Light behaves as a wave in this experiment. Light travels at a very high speed. Collisions among light particles account for the interference pattern on the screen. Question 4 (1 point) Which of the following conditions are necessary for a Young's double-slit experiment? I. The light sources must be coherent. II. The frequencies of the light sources must be equal. III. The slit separation must be much less than the distance between the slits and the screen. I and III only I and II only II and III only I, II and III I only

Question 5 (1 point) When laser light passes through a double slit, which of the following appears? a bright central band, with narrower and dimmer bands to the sides a bright central band, with equal-sized bright bands to the sides a single, wide, bright band a dark central band, with narrower and dimmer bands to the sides a dark central band, with equal-sized dark bands to the sides Question 6 (1 point) Violet light of wavelength 400 nm is incident on a diffraction grating with 5000 lines per cm. What is the highest-order fringe that can be seen in the diffraction spectrum? 5 4 3 6 Question 7 (1 point) Which of the following is true? All electromagnetic waves travel at the same speed. Electromagnetic waves can travel only in vacuum. Electromagnetic waves can travel only in material media that support wave motion, such as water and air. An electromagnetic wave is an electron waving in a magnetic field. Electromagnetic waves can be reflected, refracted, and diffracted.
