Thank you for the help!! The speed of light in vacuum (and nearly that also in air) is given the symbol c and has a value of very close to 3 x 1088 m/sec. Using values for the Index of Refraction ηη determine the value for the speed of EM waves in that medium. Look up the value of the Index of Refraction η and calculate the value for the speed of light for Polystyrene. (m/sec) Look up the value of the Index of Refraction η and calculate the value for the speed of light for Carbon disulfide CS_2 Look up the value of the Index of Refraction η and calculate the value for the speed of light for Zircon
