Understanding Sound Waves

What type of wave are sound waves classified as?

• Transverse wave

• Electromagnetic wave

• Longitudinal wave

• Surface wave

Why does sound travel faster in solids than in gases?

• Solids have particles more densely packed

• Gases have denser particles

• Gases transmit vibrations more efficiently

• Solids have more space between particles

What remains unchanged when sound waves move from one medium to another?

• Speed

• Wavelength

• Amplitude

• Frequency

What happens to the wavelength of sound as it moves into a denser medium?

• It decreases

• It becomes inaudible

• It increases

• It remains constant

Which part of the ear is primarily responsible for receiving sound vibrations?

• Auditory nerve

• Cochlea

• Eardrum

• Ear canal
