Equations and Assumptions

Relationship between Wavelength and Frequency

$$\begin{split}c &= f{\lambda} \\ c &= \textrm {speed of light} = 3.0 * 10^8 \textrm {meters per second} \\ f &= \textrm {frequency} \\ {\lambda} &= \textrm {wavelength} \\\end{split}$$

Problems

Show all your work clearly with all units and in detail, leading up to the answer:

1. An electromagnetic wave has a wavelength of 700 micrometers.

1. How many nanometers is this and what is the color of this wave?
2. What is the frequency of this wave?

2. An electromagnetic wave has a frequency of 2.0 x 10¹⁶ Hertz.

1. What is its wavelength in both nanometers and micrometers?
2. To which part of the EM spectrum does this wave belong?

3. Look up the wavelength range of red and violet light. Choose a wavelength within the range for each, and calculate their frequencies.
4. Define the concepts of wavelength and frequency of a wave, with labeled diagrams.
