Refraction of Light Objectives The objectives of this experiment are: ( l) to study light as it travels from one media to another through an interface, (2) to study Snell's law of refraction, (3) to study and learn the definition of index of refraction, (4) to study the relationship between the index of media, (5) to become familiar with the values refraction and the speed of light for a given of index of refraction for various materials, and (6) to measure the index of refraction for a glass sample.

Describe the path of a ray that approaches a mirror parallel to the principal axis.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
