change of pace = change of vibration wavelength

change of pace = change of vibration wavelength

 

point:

    1⃣ if change of pace, object send different wave

    2⃣ if pase become fast, wave length become small

    3⃣ if pase become fast, wave length become long

 

what we can with change wavelength ?

 

    1⃣ if light change vibration, temperature changes

    2⃣ if soundwave change vibration, sound changes
