Question

Enrichment Activity
Light waves are part of a family of electromagnetic waves that all travel at 3
X 108 m/s when travelling through a vacuum.
The table below shows the frequencies or wavelengths for the different parts
of the electromagnetic spectrum. Calculate the missing value in the table using the
equation below, and show your solution on the last column. One (1) check for each
black in the table and two (2) points for the correct solution.

Answer 1

Answer:

Section Summary. The relationship among the speed of propagation, wavelength, and frequency for any wave is given by vW = fλ, so that for electromagnetic waves, c = fλ, where f is the frequency, λ is the wavelength, and c is the speed of light.
