The following assumes you already know the speed of light in a vacuum.
You can do measurements related to refraction, applying Snell's law to the angles you measure. This gives you the index of refraction.Once you know the index of refraction, you divide the speed of light in the vacuum by the index of refraction, to obtain the speed of light in water.

How do you calculate velocity of water in channel?
You can calculate the velocity of water in a channel using the formula v = Q/A, where v is the velocity, Q is the flow rate of water, and A is the cross-sectional area of the channel through which the water is flowing. By knowing the flow rate and the cross-sectional area of the channel, you can determine the velocity of water.
How do you calculate the change in velocity of an object?
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
What is the velocity change when the ray of light passes from air to glass?
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
What is the velocity of light in air and water?
The velocity of light in air is about 299,792 kilometers per second, while in water it is about 225,000 kilometers per second. This difference is due to the differing refractive indexes of air and water, which affects the speed at which light travels through these mediums.
How can one calculate the velocity of water in a pipe?
To calculate the velocity of water in a pipe, you can use the formula: velocity flow rate / cross-sectional area of the pipe. The flow rate can be measured in liters per second or cubic meters per second, and the cross-sectional area is the area of the pipe's opening. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the water flowing through the pipe.
How do you calculate velocity of water in channel?

Does the air have the larges velocity of light?
The velocity of light is highest in a vaccum; slightly slower in air, and a LOT slower in water.
What happens to the velocity and wavelength of light when it passes from air into water?
The speed of the light decreases, and its wavelength increases by the same factor.

How can one Calculate the PSI of water in river based off velocity of the river?
To calculate the PSI of water in a river based on the velocity of the river, you can use the formula PSI = 0.433 * (velocity in feet per second)^2. This formula accounts for the pressure increase due to the velocity of the flowing water. Just plug in the velocity of the river in feet per second into the formula to calculate the PSI.
What is the velocity of light in air and water?
The velocity of light in air is about 299,792 kilometers per second, while in water it is about 225,000 kilometers per second. This difference is due to the differing refractive indexes of air and water, which affects the speed at which light travels through these mediums.
Which formula you use to calculate for the speed of light in water?
Speed of light in water = speed of light in vacuum/refractive index of water

If you know an objects mass and the force acting upon it you can calculate its acellaration but can you also calculate its maximum velocity If so whats the formula for this?
Yes, you can calculate the maximum velocity of an object if you know its mass, the force acting on it, and the distance it moves. The formula to calculate the maximum velocity is v = sqrt(2 * F * d / m), where v is the velocity, F is the force, d is the distance, and m is the mass of the object.
What is the formula to calculate the linear velocity of a wheel when it is rotating at a given angular velocity?
The formula to calculate the linear velocity of a wheel when it is rotating at a given angular velocity is: linear velocity radius of the wheel x angular velocity.
What is mathematical refraction?
Mathematical refraction is when we use the mathematical formula to calculate the velocity of light as it passes from one medium to another.
