Question

refer to figure 1 above. what type of wave is illustrated in the figure?

1. the type of wave is an electromagnetic or transverse wave because all sound waves are t
2. more information is required to determine the type of wave in the figure.
3. the wave is an electromagnetic wave because the wavelength is measurable
4. the type of wave is a mechanical or longitudinal wave because the compressions and rarefa

Explanation:

The figure shows a tuning - fork creating waves in a medium with areas of compression and rarefaction. Mechanical or longitudinal waves are characterized by compressions and rarefactions. Sound waves are mechanical longitudinal waves. Electromagnetic waves are transverse and do not require a medium and do not have compressions and rarefactions as shown in the figure.

Answer:

D. The type of wave is a mechanical or longitudinal wave because the compressions and rarefactions are visible.
