A drum is struck, producing a wave with a wavelength of 110 cm and a speed of
2.42 × 104 m/s. What is the frequency of the wave? What is the period?

Answer :

Explanation:

wavelength = l

speed of wave = v

frequency = f

v = lf → f = v/l = 2.42 × 10⁴ ÷ 1.1 = 2.2 × 10⁴ 1/s

T = 1/f = 1/ 2.2 × 10⁴ = 0.45 × 10 -⁴ s
