Abeam of light traveling through a liquid (of index of refraction n1 = 1.47) is incident on a surface at an angle of θ1 = 59° with respect to the normal to the surface. it passes into the second medium and refracts at an angle of θ2 = 69° with respect to the normal. randomized variablesn1 = 1.47θ1 = 59°θ2 = 69°part (a) write an expression for the index of refraction of the second material. part (b) numerically, what is this index? part (c) numerically, what is the light's velocity in medium 1, in meters per second? part (d) numerically, what is the light's velocity in medium 2, in meters per second?

1. when conducting a test on what kind of music increases the growth of plants, all of the following would fail to meet to fair test standard except (1 point) using different kinds of plants. giving some plants more water than others. exposing the plants to different types of music. using nutrient-rich soil for one and lesser soil for others. 2. engineering uses scientific thinking to solve real-world problems. (1 point) true false 3. what does it mean to test a hypothesis? (1 point) pass a quiz on other scientists’ results analyze only the results from scientific sources not make assumptions about how an experiment will turn out see if the results of an experiment are what the scientist predicted
