The speed of propagation, c, of a capillary wave depends on the density of the fluid, ρ, the wavelength of the wave, λ, and the surface tension, σ. If the density and wavelength remain constant, halving the surface tension would lead to a new velocity, c', given by
- A. c' = 2c
- B. c' = √2c
- C. 𝑐ᇱൌ √ଶ
- D. c' = c
Answer: C. 𝑐ᇱൌ √ଶ
