AP1200 Quiz 4 Student Name ____________________________ Student ID ___________________ 1. A student reading his physics book on a lake dock notices that the distance between two incoming wave crests is about 2.4 meters, and the time of arrival between the two wave crests is about 1.6s. What is the approximate speed of the waves? Answer The speed of the wave is: v = λ f = λ /T = 2.4/1.6 = 1.5m/s 2. What types of wave motion can propagate in (a) solids, (b) liquids, and (c) gases? Answer There are two types of basic mechanical waves: transverse wave and longitudinal wave.

Unformatted text preview: Part I (a) Both transverse and longitudinal waves will propagate in solids (b) Only longitudinal wave will propagate in liquids (c) Only longitudinal wave will propagate in gases Part II (This part is not required in the quiz) Surface waves are also considered as mechanical waves that travel along the boundary between two mediums. A water wave is an example of a surface wave, which is a combination of transverse and longitudinal wave motions. Electromagnetic waves are transverse waves. They propagate in solids, liquids, gases and vacuum....
