How do you do these multiple choice questions? WaveTwo tin cans are attached by a horizontal string that is pulled taught, as shown. When a student speaks into the can onthe left, the student's voice can be heard in the can on the right, because the disturbance caused by the student's voice iscarried by a wave that travels the length of the string from the left to the right. Which of the following best describes thewave that carries the student’s voice?(A) The wave is a longitudinal wave, because the molecules in the string oscillate right and left.(B) The wave is a longitudinal wave, because the molecules in the string oscillate up and down.(C) The wave is a transverse wave, because the molecules in the string oscillate right and left.(D) The wave is a transverse wave, because the molecules in the string oscillate up and down.An object with a height of 7 cm is located 14 cm from a converging lens. If the image is located 28 cm from the lens,what is the height of the image?(A) 2 cm(В) 3.5 сm(С) 14 сm(D) 56 cm123A beam of light travels through materials 1, 2, and then 3, as shown. Wave fronts of the beam within each material arerepresented as parallel lines. Which of the following is a correct statement about the propagation speed of light in thesematerials?(A) The propagation speed of material 3 cannot be compared with that of material 1, because these materials are notadjacent to one another.(B) The propagation speed in material 2 is lower than the propagation speed in materials 1 and 3, because the angleof the beam entering and leaving materials 2 is steeper than within this material.(C) The propagation speed in material 2 is higher than the propagation speed in materials 1 and 3, because the wavefronts are farther apart.(D) The propagation speed in material 2 is equal to the propagation speed in materials 1 and 3, because thepropagation speed of light is c.
