huh said:What would happen if antinodes were at the ends instead of nodes?

Standing waves with antinodes at the ends refer to a type of wave pattern that occurs when two waves with the same frequency and amplitude travel in opposite directions and interfere with each other. This results in nodes (points of no movement) and antinodes (points of maximum movement) at specific locations along the wave.
To create standing waves with antinodes at the ends, you need to have two waves with the same frequency and amplitude traveling in opposite directions and interfering with each other. This can be achieved by using a medium, such as a string or air column, and a source of oscillation, such as a vibrating object or speaker, at both ends of the medium.
Standing waves with antinodes at the ends have several distinct properties, including a fixed wavelength, nodes and antinodes at specific locations, and no overall movement of the medium. They also have a characteristic frequency, which is determined by the length of the medium and the speed of the waves.
Standing waves with antinodes at the ends have various practical applications, including in musical instruments, such as stringed instruments and wind instruments, where they produce distinct harmonics. They are also used in resonance experiments and in medical imaging techniques, such as ultrasound.
The formation of standing waves with antinodes at the ends is affected by several factors, including the frequency and amplitude of the waves, the length and properties of the medium, and any external forces or disturbances. These factors can alter the wavelength, frequency, and overall pattern of the standing wave.
