My youngest, since leaving for college last fall, was home for 4 weeks at Christmas, is now home for a 2 week spring break, and will be here a couple of times over the summer, with the longest stretch being about 6 weeks. He went to a friend's house for Thanksgiving.
What are Sneaker Waves? Sneaker waves are unusually large ocean waves that appear suddenly and without warning. Small children should be watched around the ocean to protect them from the sudden dangers associated with sneaker waves.
Definition of Mechanical Waves. A mechanical wave is a wave that is a vibration in matter, transferring energy through a material. Not all waves are like this. For example, electromagnetic waves such as visible light are not mechanical because they can travel through the vacuum of space to reach us from the sun. Mechanical waves include water waves, sound waves, earthquake waves, and many more. Like all waves, those of the mechanical variety have peaks, or crests, and troughs. They also have a frequency, which is the number of waves that pass by per second, and a wavelength, which is the distance from one peak to the next, or one trough to the next.
