1338 - What are the characteristics of a wave, such as crest, trough, wavelength, frequency, wave speed, and amplitude.

Let's break down the parts of a wave in a simple way:

1. Crest: The highest point of the wave. It's the top part where the wave looks like a hill.
2. Trough: The lowest point of the wave. It's the bottom part where the wave looks like a valley.
3. Wavelength: The distance from one crest to the next crest (or trough to trough). It's like measuring how long the wave is.
4. Frequency: How many waves pass a certain point in a second. It's like counting how many waves you see going by in a minute.
5. Wave speed: How fast the wave is moving. It's like how quickly the wave is traveling through the water or air.
6. Amplitude: How high the wave is from the middle point (called the 'resting point'). It's like measuring how big the wave is.

Think of it like this: Imagine you're at the beach, and you see a big wave coming towards you. The crest is the top part of the wave, the trough is the bottom, the wavelength is how long it is, the frequency is how many waves come by in a minute, the speed is how fast it's moving, and the amplitude is how tall the wave is from the regular water level.
