______________ The hydrogen gas spectrum is seen in the image on the left. Is this a continuousordiscrete sprectrum?
______________ The lines from left to right are red, cyan, and purple. Which of these three has the longest wavelength (which is the same as saying "the lowest frequency")?
___________________ What is the box-like object in the picture with the candle called?
_____ A laser is beamed into a semi-circular dish of water. Will the light come out at A or B?
In the diagram, draw the path of a light ray from the penny to the eye.
Plot the data below on the graph provided and draw a linear best fit line through the data points on the graph.
______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
______________ The above material is reported to have a theoretic index of refraction of 1.33. What is the percentage error for the slope you calculated based against a theoretic value of 1.33?
