U-shaped valley
If a wave has a very short wavelength, what can you say about its energy and frequency?
It has high energy and high frequency

Fertilization cannot occur because sperm and egg cannot meet
How can sexual selection affect the traits of a population over time?
Traits preferred in mates become more common in the population
