Problem

A popular kitchen appliance produces electromagnetic radiation with a frequency of 2450 MHz.

With reference to the figure below 

A diagram showing the electromagnetic spectrum, which ranges from low frequency (long wavelengths) to high frequency (short wavelengths).,

answer the following:

Using the diagram, determine whether the wavelength of the appliances radiation belongs to the visible region of the electromagnetic spectrum. Based on your finding, would the appliances radiation be visible to the human eye?

Solution

We are being asked to determine if the wavelength of the appliances radiation belongs to the visible region of the electromagnetic spectrum, and if it will be visible to the human eye. We're given the frequency 2450 MHz.


Let's first convert the frequency of the appliance radiation from MHz to Hz or s-1.

Recall:      1 MHz = 106 Hz

                  Hz = s-1
