Using the wave equation v = fλ, we can find the wavelength: λ = v/f = 340 m/s / 1700 Hz = 0.2 m.

Using the wave equation v = fλ, we can find the wavelength: λ = v/f = 340 m/s / 680 Hz = 0.5 m.

Using the wave equation v = fλ, we can find the wavelength: λ = v/f = 340/170 = 2 m.

Sound travels faster in water than in air, so its speed increases when it enters water.

Wavelength λ = v/f = 340 m/s / 1700 Hz = 0.2 m.

Wavelength λ = v/f = 340 m/s / 1700 Hz = 0.2 m.

Wavelength = Speed / Frequency = 340 m/s / 1700 Hz = 0.2 m.

Using the formula v = fλ, we can rearrange to find λ = v/f. Thus, λ = 340 m/s / 1700 Hz = 0.2 m.

Wavelength λ = v/f = 1500 m/s / 300 Hz = 5 m.

Using the formula λ = v/f, we find λ = 340 m/s / 440 Hz = 0.7727 m, approximately 0.77 m.

The period T is the reciprocal of frequency f. T = 1/f = 1/440 Hz = 0.00227 s.

The period T is the reciprocal of frequency f. T = 1/f = 1/440 Hz = 0.00227 s.

The wavelength λ can be calculated using the formula λ = v/f, where v is the speed of sound and f is the frequency. Thus, λ = 340 m/s / 440 Hz = 0.77 m.

The speed of sound in air at 20°C is approximately 343 m/s. The wavelength λ is given by λ = v/f. Thus, λ = 343/440 ≈ 0.78 m.

Wavelength λ is given by the formula λ = v/f. Here, v = 340 m/s and f = 440 Hz. Thus, λ = 340/440 = 0.7727 m, approximately 0.77 m.

Speed v = f × λ = 50 Hz × 2 m = 100 m/s.

Speed v = f × λ = 50 Hz × 3 m = 150 m/s.

The speed v of a wave is given by v = fλ. Here, v = 600 Hz * 0.5 m = 300 m/s.

The maximum speed v_max is given by v_max = ωA, where ω = 2πf. Thus, ω = 2π(10) = 20π and v_max = 20π(0.5) = 10π ≈ 31.42 m/s.

The amplitude of the wave is the coefficient of the cosine function, which is 0.2 m.

The amplitude of the wave is the coefficient of the cosine function, which is 0.05 m.

The speed of the wave v is given by v = fλ. Here, f = 10 Hz and λ = 2 m (from k = 2π/λ). Thus, v = 10 * 2 = 20 m/s.

The speed of the wave v is given by v = ω/k. Here, ω = 2π(2) = 4π rad/s and k = 2π(0.5) = π rad/m. Thus, v = (4π)/(π) = 4 m/s.

The amplitude is the coefficient of the sine function, which is 0.1 m.

'A' represents the amplitude of the wave, which is the maximum displacement from the equilibrium position.

'k' is the wave number, which is related to the wavelength of the wave.

The wave speed v can be found from the equation v = fλ. Here, f = 4 Hz and λ = 2 m (from k = 2π/λ, k = 1 m⁻¹). Thus, v = 4 Hz * 2 m = 8 m/s.

The speed of the wave v is given by v = fλ. Here, f = 2 Hz and λ = 1 m (from the wave equation). Thus, v = 2 * 1 = 2 m/s.

'A' represents the amplitude of the wave, which is the maximum displacement from the equilibrium position.
