A student woke up in the morning and checked the rain gauge in her backyard. The rain gauge was empty, but the grass was moist.
Which of the following best explains how this could happen?
A. It snowed, but did not rain during the night.
B. Run-off from a nearby river made the grass wet.
C. Water Vapor Condensed on the grass.
D. The water in the rain gauge evaporated, but the water on the grass did not.
Explain why you choose the answer you did.

Answer:
Wavelength,
Explanation:
Given that,
Number of cycles in a spiral spring is 2.91 in every 3.67 s
The velocity of the pulse in the spring is 0.925 cm/s, v = 0.00925 m/s
To find,
Wavelength
Solution,
Number of cycles per unit time is called frequency of a wave. The frequency of the longitudinal pulse is,
The wavelength of a wave is given by :
So, the wavelength of the longitudinal pulse is 0.011 meters. Hence, this is the required solution.
