"When light propagates through a material, it travels slower than the vacuum speed, c. This is a change in the phase velocity of the light and is manifested in physical effects such as refraction. This reduction in speed is quantified by the ratio between c and the phase velocity. This ratio is called the refractive index of the material. Slow light is a dramatic reduction in the group velocity of light, not the phase velocity. Slow light effects are not due to abnormally large refractive indices, … " - Slowest speed of light recorded

WebbSolution: We know that the speed of sound is given by the formula: v = λ ν. Substituting the values in the equation, we get. v = 0.35 m × 2000 Hz = 700 m/s. The time taken by the sound wave to travel a distance of 1.5 km can be calculated as follows: Time = Distance Travelled/ Velocity.
