Electromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation. While these forms of energy might seem quite different from one another, they are related in that they all exhibit wavelike properties.

Keep in mind that some waves (including electromagnetic waves) also oscillate in space, and therefore they are oscillating at a given position as time passes. The quantity known as the wave’s frequency refers to the number of full wavelengths that pass by a given point in space every second; the SI unit for frequency is Hertz (\text{Hz})(Hz)left parenthesis, start text, H, z, end text, right parenthesis, which is equivalent to “per seconds” \Big((left parenthesiswritten as \dfrac{1}{\text{s}}

c=\lambda \nuc=λν

A particular wave of electromagnetic radiation has a frequency of 1.5\times10^{14}\text{ Hz}1.5×10

What is the wavelength of this wave?

We can start with our equation that relates frequency, wavelength, and the speed of light.

c=\lambda \nuc=λνc, equals, lambda, \nu

Next, we rearrange the equation to solve for wavelength.

\lambda=\dfrac{c}{\nu}λ=

Lastly, we plug in our given values and solve.

\lambda=\dfrac{3.00\times10^8\dfrac{\text{m}}{\cancel{\text{s}}}}{1.5\times10^{14}\dfrac{1}{\cancel{\text{ s}}}}=2.00\times10^{-6}\text{ m}λ=

Concept check: What would you expect to happen to the frequency of a light wave if its wavelength were increased by a factor of 101010?

Period

The last quantity we will consider is the period of a wave. A wave’s period is the length of time it takes for one wavelength to pass by a given point in space. Mathematically, the period (TTT) is simply the reciprocal of the wave’s frequency (fff):

T=\dfrac{1}{f}T=

The units of period are seconds (\text{s}sstart text, s, end text).

Now that we have an understanding of some basic properties of waves, we’ll look at the different types of electromagnetic radiation.
