Problem 2PE

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.

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to calculate the wavelengths and frequencies of the given radiation. Step1: The distance between two adjacent crests or troughs is called wavelength. It is denoted by the o o -10 greek letter lambda() and is generally expressed in terms of Angstrom units(A ) [1 A = 10 m] On the other hand, the number of waves which pass through a given point in one second is known as the frequency. It is denoted by the greek letter nu() and is generally expressed in -1 terms of Hertz(Hz) [1 Hz = 1 sec ] If c is the velocity of light, the the relation between wavelength, frequency and velocity of...
