QUESTION:

Problem 2PE

Calculating Frequency from Wavelength

The yellow light given off by a sodium vapor lamp used for public lighting has a wavelength of 589 nm. What is the frequency of this radiation? (a) A laser used in orthopedic spine surgery produces radiation with a wavelength of 2.10 pm. Calculate the frequency of this radiation, (b) An FM radio station broadcasts electromagnetic radiation at a frequency of 103.4 MHz (megahertz; 1 MHz = 106 s-1). Calculate the wavelength of this radiation. The speed of light is 2.998 x 108 m/s to four significant figures.
