Want this question answered?
Radiowaves are the lowest, with microwaves a close second in lowest frequency.
You are supposed to use the basic formula for waves: speed = wavelength x frequency. In this case, you have to solve for frequency. (The period is the reciprocal of the frequency.)
which kind of sound is produced by sound waves with peaks that are very close together?
longitudinal waves spread apart as they go
This question is misguided. It is not the sound waves which are apart, but the particles of the medium. A place where the particles are further apart is called a rarefaction. Where they are crowded together is called a compression.
Pitch is another name for the frequency of sound waves . . . that is, how close the waves are together. Pitch is a term usually used in terms of music.
Frequency = 1/period = 1/10 sec = 0.1 Hz.

No The pitch you hear is determined by the frequency of the sound wave (how fast the particles oscillate back and forth). Higher frequency => higher pitch.

which kind of sound is produced by sound waves with peaks that are very close together?
speed of a wave = wavelength x frequency = 2.5m x 4Hz = 10m/s
Yes! P-waves are indeed compression or longitudinal waves which push the crust together and pull it apart as they travel. They are also able to travel through liquids and gasses, unlike S-waves (shear or transverse waves) which can only travel through solids.

Frequency is how close waves follow one another, usually given for one second of time. This can alos be measure in the length between successive waves. For example, a frequency of 14.5 megaHertz has a wavelength of about 20 meters. For electromagnetic waves, the relationship is simple: Energy of the photon equals the frequency of the EM wave times Planck's Constant.
