  1. What does the peak wavelength on a spectral curve tell you about a star? What can astronomers tell from a sepctral curve
  2. What two parts does a light wave consist of? Light does not require a ____________. A particle of light is called a _____________. What is meant by “wave-particle duality”? What are the divisions of the EM spectrum. In order. What are three ways the electromagnetic spectrum is arranged and indicate the direction of their magnitude What does c=ƒ mean? What is the relationship of  and ƒ What is the wavelength of a light wave that has a frequency of 595 THz ( 1 THz = 1012 Hz)? In nanometers Show work
