What is the speed of the component wave?
What is the speed of the component wave?
- A. \( 120 \mathrm{cm} / \mathrm{s} \)
- B. 240 cm/s
- C. \( 143 \mathrm{cm} / \mathrm{s} \)
- D. \( 287 \mathrm{cm} / \mathrm{s} \)
Step-by-step solution
Without additional context, the most common wave speed calculation involves multiplying frequency and wavelength. For instance, if a wave has a frequency of 2 Hz and a wavelength of 1.2 m, then v = fλ = 2 Hz × 1.2 m = 2.4 m/s = 240 cm/s. This is a typical result.
