### Homework Problem 1A #3

In problem 1A.3, what does it mean by the “extent of change in the electrical field”? Is it referring to the amplitude of the wave? In that case, if the frequency decreases, will the extent of change also decrease?

the "extent of the change" means the slope of the wave. Then, as frequency decreases, amplitude decreases (the waves get farther apart) and the extent of the change decreases.

As frequency decreases, wavelength increases. As wavelength increases, the slope of each wave decreases as the waves appear less steep. Slope = extent of change, therefore the extent of change decreases. Also, it always helps me to draw it out :)

the extent of change refers to the wave's slope, which correlates directly with frequency.
