Consider a simple example of a guitar string. When you pluck a guitar string it may vibrate such that it forms a half sine wave when it vibrates (i.e. has only one crest in the center) or have a complete sine wave (i.e. has one crest and one trough along the length of the string) or have multiple sine waves on it. Each of these "forms" in which a string can vibrate are called mode shapes of vibration
