Since the 20th century, human understanding of strings has undergone a qualitative change. Strings are vibrations, and vibrations generate waves, indicating that waves constitute a rich and colorful world, which provides an ideological basis and technical methods for re-understanding "beauty". Studies have shown that there is a deep internal relationship between natural beauty and the wavelength (or frequency) of matter. The natural frequency of an object has a coupling relationship with the human's own frequency. "Beauty" is caused by the interaction between the frequencies of different types of the spectrum and people. produced. According to this text, the following statements are incorrect:. ["Different understandings of the same person's beauty and ugliness are due to different frequencies of aesthetic subjects.", 'Sunlight, flowers are generally unchanged for a certain period of time, because the vibration frequency does not change.', 'Distance produces beauty because the aesthetic subject and object resonate in a certain frequency range.', 'Seeing social courage for behavior, because aesthetic subjects have the same frequency of vibration.']
