A piano creates sound waves of different pitches by striking a small hammer against the strings inside the instrument. When a key is struck, the corresponding hammer strikes a string, causing a vibration that creates a sound wave. How do the sound waves of the higher pitch notes compare to the sound waves of the lower pitch notes?

• The sound waves of notes with higher pitches travel at higher speed.

• The sound waves of notes with higher pitches have higher amplitudes.

• The sound waves of notes with higher pitches have higher frequencies.

• The sound waves of notes with higher pitches have higher wavelengths.

Which of the type of electromagnetic waves is correlated to the following... satellite?

• radio waves

• microwaves

• infrared waves

• gamma rays

Which electromagnetic wave has the shortest wavelength?

• X-rays

• Gamma Rays

• Radio Waves

• Microwaves

When a transverse wave moves through a medium, how do the particles of the medium respond?

• They remain at rest as the wave passes.

• They travel through the medium with the wave

• They vibrate in a direction parallel to the direction in which the wave is moving.

• They vibrate in a direction perpendicular to the direction in which the wave is moving.
