Solution: Consider the two waves shown here, which we will consider to represent two electromagnetic radiations.What is the wavelength of wave A?

Problem

Consider the two waves shown here, which we will consider to represent two electromagnetic radiations.

What is the wavelength of wave A?

A diagram shows that over a distance of 1.6 times 10 to negative 7 meters, wave A completes 3 and ¾ cycles and wave B completes two cycles.

Solution

We are asked to determine the wavelength of wave A in the figure:

A diagram shows that over a distance of 1.6 times 10 to negative 7 meters, wave A completes 3 and ¾ cycles and wave B completes two cycles.

Recall that a wavelength is the distance wherein a wave repeats. Let us assign the wavelengths of the waves given:
