Answer 2

To find the value of S², we can use the formula for the relationship between the surface area (S) and the frequency (f) of a wave:

S¹ / S² = (f² / f¹)²

Given: f¹ = 400 Hz S¹ = 2 cm² f² = 20 kHz (Note: kHz means kilohertz, which is equal to 1000 Hz)

Let's substitute these values into the formula:

S¹ / S² = (f² / f¹)² 2 cm² / S² = (20 kHz / 400 Hz)² 2 cm² / S² = (20,000 Hz / 400 Hz)² 2 cm² / S² = 50² 2 cm² / S² = 2500

Now, let's solve for S² by rearranging the equation:

S² = 2 cm² / 2500 S² = 0.0008 cm²

Therefore, S² is equal to 0.0008 square centimeters.
