This time, make a wave while moving your hands fast.
You have probably seen a wave, but have you created one? Let's try and make
some waves.
Get a rope of any kind and tie one end of it to a fixed sturdy object near you.
Now, straighten the rope and hold the other end of it. Start moving your hands up and down. Observe what happens to the rope. Were you able to make a wave? Draw the wave you made on a separate sheet of paper.
Now, try to make a wave again but move your hands slowly. Observe what
happens.
Based on the activity, is there any difference on the waves you have created? Why does each created wave look differently?
Answer (1)
Answer: What Happened?When you moved your hands fast:The rope created more waves or smaller, tighter waves.These waves moved quickly and looked sharp or frequent.This type of wave has a shorter wavelength and a higher frequency.When you moved your hands slowly:The rope created fewer, longer waves.The waves appeared more gentle or spread out.This type of wave has a longer wavelength and a lower frequency. Why Are They Different?Each wave looks different because of how fast you moved your hand—this changes the frequency of the wave:Frequency is how many waves are made in a certain amount of time.Faster hand movement = more waves = higher frequency.Slower hand movement = fewer waves = lower frequency.The energy you give the rope by moving your hand is what creates the wave. The faster and stronger you move, the more energy goes into the wave, and that affects how it looks. Drawing the Waves (to do on your paper):Draw two ropes:One with many tight waves (for fast movement).One with fewer, wide waves (for slow movement).Label them as "High Frequency Wave" and "Low Frequency Wave".✅ Conclusion:Yes, there is a clear difference in the waves you created! The speed of movement affects the frequency and shape of the wave. This is a great way to understand how waves behave in science—whether it's on a rope, sound waves, or even ocean waves.
