Waves transfer energy over distance without moving matter the entire distance. So your answer would be energy.
Answer:
The speed of light is faster in water. The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.
F₁ = c / d²
F₂ = c / (3d)²
F₁/F₂ = 3² = 9
F₂ = 1/9 F₁
