Please answer all questions completely. If calculations are required, show enough steps so that I can follow your reasoning.
#1, What is meant by "wavelength"?
#2 What is meant by the "period" of a wave?
#3. You are sitting on a beach watching the waves roll in. In 12 seconds, 6 waves roll by. What is the period of the waves (T)? What is their frequency? (f)
#4 What is the speed of light in a vacuum?
#5 An AM radio station broadcasts at a frequency of 660 kHz. (note that k means 1000) Since radio waves move at the same speed as light waves, what is the wavelength of this radio wave?
#6 Compare your answer to problem #4 to the example on page 7, which is for an FM station broadcasting at 100 MHz (M = 1 000 000). Which type of broadcast, AM or FM, has longer wavelength waves?
#7 List the electromagnetic spectrum in order of INCREASING wavelength (shortest to longest).
#8 List the colors of the visible spectrum in order of INCREASING wavelength (shortest to longest).
#9 What colors correspond to the following wavelengths:
a)450 nmb)550 nm
c)650 nm
#10 What is an instrument that allows scientists to study light spectra?
