Question
Sentences of a paragraph are given below in jumbled order.
Arrange the sentences in the correct order to form a meaningful and coherent paragraph. (A) These ultrasonic waves are emitted from two transducers and shaped by 3D-printed structures called metasurfaces. (B) When the two ultrasonic beams intersect, a local nonlinear interaction generates an audible sound wave, which is only heard at that specific point of intersection.(C) Researchers have developed a method that uses two non-linear ultrasonic waves to create an audible sound only at a specific point in space.(D) The metasurfaces allow the ultrasonic beams to bend around obstacles, such as human heads, and intersect at a specific target location.Solution
The correct sequence is CADB.
C introduces the topic by explaining what the researchers have developed — a method that uses non-linear ultrasonic waves to create sound.
A follows up by explaining how these ultrasonic waves are emitted and shaped, providing technical details.
D elaborates on how metasurfaces help bend the ultrasonic beams around obstacles, providing more context on how the technology works.
B concludes the paragraph by describing what happens when the two ultrasonic beams intersect, creating the audible sound.
