Instructions: Based on the information present in the given passage, you need to write a correct answer to the given question. A correct answer is one that correctly and completely answers the question. Do not write answers that address the question partially or incorrectly. The correct answer must be contained in the given paragraph.
Input: Paragraph- Sent 1: The highest point of a wave is the crest.
Sent 2: The lowest point is the trough.
Sent 3: The vertical distance between a crest and a trough is the height of the wave.
Sent 4: Wave height is also called amplitude.
Sent 5: The horizontal distance between two crests is the wavelength.
Sent 6: Both amplitude and wavelength are measures of wave size.
Sent 7: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows.
Sent 8: The greater each of these factors is, the bigger a wave will be.
Sent 9: Some of the biggest waves occur with hurricanes.
Sent 10: A hurricane is a storm that forms over the ocean.
Sent 11: Its winds may blow more than 150 miles per hour!
Sent 12: The winds also travel over long distances and may last for many days. 
Question: What do we know about wavelength from the paragraph?.
Output:
It is the distance between two crests, and is a factor in wave size.
