What does the dashed line represent?

• sound in air

• sound in water

• threshold of hearing

• threshold of pain

Based on the figure, sound intensity is greatest in

• air for any value of S

• water for any value of S

• air at S = 10^-8 % only

• water at S = 10^-8 % only

• how sound waves are generated

• how sound travels differently in air versus water

• scientific notation (powers of ten)

• how ears interpret sound
