Answer the following questions based on your interpretation of the Electromagnetic Spectrum chart

of the Earth Science Reference Tables (page 14) as well as your class notes.

1. Visible light consists of which range of wavelengths (in centimeters) of electromagnetic energy?

a. 4.0 x 10exp-5 to 7.0 x 10exp-5 b. 1.0 x 10exp-10 to 1.0 x 10exp3

c. 1.0 x 10exp-6 to 1.0 x 10exp1 d. 5.0 x 10exp-4 to 5.0 x 10exp-7

light, given that wavelength and frequency are inversely proportional?

a. longer wavelength and higher frequency b. longer wavelength and lower frequency

c. shorter wavelength and higher frequency d. shorter wavelength and lower frequency

3. Which form of electromagnetic energy possesses the highest frequency?
