<span>The volume of water that moves past a point on a river in a given time is called the river’s DISCHARGE or FLOW RATE. The flow rate is used to measure and study bodies of water to better understand how they work. It is useful in areas such as wastewater treatment. Water flow or velocity typically increases as the the depth or hydraulic radius of the river increases.</span>

Answer:
The wavelength of the light passing through it. (Ans B).
Explanation:
The refractive index of a substance is defined as the ratio of the speed of the light present in the vacuum to the speed in the medium. Refractive index of a substance is called as a dimensionless number that helps to describe how fast light will travel through the substance. It is described as:
N = C/V,
Where C is known for the speed of the light in vacuum, and V is known as the phase velocity of light which is found in medium.
