A)24.8 m/s.
B)36.2 m/s.
C)70.8 m/s.
D)84.6 m/s.
E)98.7 m/s.

Quizplus · Accepted Answer

The speed of the wave can be calculated using the formula:

v = λf

where v is the speed of the wave, λ is the wavelength and f is the frequency.

Substituting the given values, we get:

v = 0.145 m × 488 Hz = 70.76 m/s ≈ 70.8 m/s

Therefore, the correct option is (C) 70.8 m/s.
