Imagine a diagram of a simple wave oscillating up and down. Four points are labeled on this wave: Point A is at the very highest point. Point B is on the downward slope, halfway between the highest point and the central line. Point C is on the central line itself. Point D is on the upward slope. Which labeled point represents a peak?

Frequency of a Wave

Inverse Relationship Between Wavelength and Frequency

Imagine four different waves are measured. Which of the following descriptions represents the wave with the longest wavelength?

Consider two distinct waves, Wave A and Wave B. For Wave A, the measured distance from the highest point of one wave to the highest point of the very next wave is 10 nanometers. For Wave B, the same measurement is 20 nanometers. Based on an analysis of this information, what can you conclude?
