Answer

Infrasound is characterized as longitudinal waves, while infrared radiation is classified as transverse. Therefore, the correct option is:

C: infrasound - longitudinal, infrared - transverse.

Put a cross (X) in box C.

Step 2

Answer

Infrasound refers to sound waves with frequencies below the range of human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above human hearing (above 20 kHz). Infrasound can travel long distances and penetrate through various mediums, making it useful for monitoring natural phenomena, whereas ultrasound is typically used in medical imaging and industrial applications due to its higher frequency and shorter wavelength.
