Which of the following would NOT be considered a mechanical wave?
Surface wave on the ocean
Radio wave transmitted from a satellite
Standing wave on a guitar string
Sound wave in a pipe organ
which one can't you feel?
To determine which of the following would NOT be considered a mechanical wave, let's first understand what a mechanical wave is.
A mechanical wave is a type of wave that requires a medium (substance) to transmit its energy. The medium can be solid, liquid, or gas, but it must be present for the wave to travel. Mechanical waves transfer energy through the vibration or oscillation of particles within the medium.
Now, let's analyze the given options:
1. Surface wave on the ocean: This is a mechanical wave. It is caused by the interaction of wind with the surface of the water, which transfers energy to the water particles and creates a wave.
2. Radio wave transmitted from a satellite: This is not a mechanical wave. Radio waves are a type of electromagnetic wave, which do not require a medium to propagate. They can travel through a vacuum (empty space) and are created by the oscillation of electric and magnetic fields.
3. Standing wave on a guitar string: This is a mechanical wave. When a guitar string is plucked or strummed, it vibrates and creates a standing wave pattern. The wave transfers energy through the collision of adjacent particles in the string.
4. Sound wave in a pipe organ: This is a mechanical wave. Sound waves are created by vibration, typically from a source like a musical instrument or vocal cords. They travel through a medium, such as air or other materials, by causing particles to oscillate and transfer energy.
Therefore, the option that would NOT be considered a mechanical wave is "Radio wave transmitted from a satellite."
