- Mark off 10 10-cm intervals from the vertical line. Starting at the first interval, label each mark as a whole number times 1014, from 1 x 1014 to 10 x 1014. Label the bottom of your model "Frequency in Hertz." You can now plot some of the 1014 frequencies you calculated on the bottom line of your constructed model. Plot the individual colors of the visible spectrum and color them. Compare the two scales. Do the results surprise you?
- How far does the ultraviolet band extend? Calculate the width of the X-ray band. Do you have enough string to measure the distance from the end of the ultraviolet band to the end of the X-ray band? What do you think you would need to measure the distance to the end of the X-ray part of the EMR?
- X-rays are the next band of radiation. Calculate the distance from the end of the ultraviolet band to the end of the X-ray band. Obtain a map from the Internet or use a local or state highway map to plot the distance.
- This URL will be useful in measuring the distance from the end of your string (the end of the ultraviolet band) to the end of the X-ray band: Yahoo! Maps.
- Based on your results for the width of the X-ray band, what would be your estimate for the width of the gamma ray band of radiation? What would you need to measure the distance?
