What was the focal length when the radius of curvature was 0.70 m and index of refraction was 1.8?
The focal length of a lens is related to its radius of curvature and the index of refraction by the lensmaker's equation: [\frac{1}{f} = (n-1) \left( \frac{1}{R_1} - \frac{1}{R_2} \right)] Given the radius of curvature (R = 0.70 , m) and the index of refraction (n = 1.8), you can calculate the focal length.
How we can calculate the velocity of light in water?
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.
Is there formula of force?
Force is equal to mass times acceleration. This is Newton's Second Law.
What force acts on a mass of 2kg?
The force acting on a mass is given by the equation F = m*a, where F is the force, m is the mass, and a is the acceleration. If the mass of an object is 2kg and it is experiencing an acceleration, a force will be acting on it according to Newton's second law.
What is the formula of the force and motion?
The formula for force (F) is given by Newton's second law: F = m * a, where m is the mass of an object and a is its acceleration. The formula for motion is given by the equation x = x0 + v0 * t + (1/2) * a * t^2, where x0 is the initial position, v0 is the initial velocity, a is the acceleration, t is time, and x is the final position.
How do you use snell's law to find the speed of light in jello?
Snell's law combines trigonometry and refractive indices to determine different aspects of refraction. The law is as follows: (n1)(sinX1) = (n2)(sinX2); where n1 is the refractive index of the first medium, X1 is the angle of incidence (the angle between the incident ray and the normal), n2 is the refractive index of the second medium, and X2 is the angle of refraction (the angle between the refracted ray and the normal). Setting up an experiment using jello and a laser, one can determine the index of refraction in the jello. Shine the laser at an arbitrary angle and record this angle. Then measure the refractive angle seen in the jello (this is the angle between the ray in the jello and the normal). The index of refraction for air is 1.0003. Now substitute all three values into Snell's law and solve for n2, the refractive index of jello. An index of refraction is defined as the speed of light in a vacuum divided by the speed of light in a medium. Once n2 is determine, use the following equation: n2 = c / v. Substitute n2 and the speed of light in a vacuum (which is approximately 299,792,458 meters per second), and solve for v. The value obtained will be the speed of light in jello.

The speed of light in a particular type of glass is 1.60 X 108 What is the index of refraction of the glass?
The index of refraction, or optical density, is the ratio of the speed of light in a vacuum to that in a given material. Therefore, the index of refraction for this glass is equal to c / v = (3.0 x 10^8 m/s) / (1.6 x 10^8 m/s) = 3.0/1.6 = 1.88

What is the acceleration of the system given the value of f and m?
Newton's Second Law: F=ma. Solving for a: a = F/m.
Who do objects that lie half in and half out of water appear distorted?
refraction -- light has a lower velocity in medium other than a vacuum, where light achieves the highest velocity (~3E8 m/s). In general, the denser the medium, the slower the speed. The actual relation is expressed as Snell's law, which relates the indices of refraction to the angles of entrance and exit relative to the normal. When light travels from one medium to a different medium, the path changes its direction right at the boundary (the angle of incidence is different from the angle of refraction), giving your eyes an illusion of the part of the object submerged in water being located a distance away from its actual location.
When light moves from a material in which its speed is higher to one in which its speed is lower what the ray is?
When light moves from a material in which speed is higher to a material in which its speed is lower it is REFRACTED, i.e, it is deviated from its original path, according to the laws of refraction which are as follows:The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane.For any two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.The above law is called Snell's law after the scientist Willebrod Snellius who first formulated it(sin i/sin r)=constant =m. ThusWhere m is the refractive index of the second medium with respect to the first medium.for e.g.the refractive index of glass with respect to air is given asratio of -speed of light in air to speed of light in glass.(when light passes from air to glass)
If the index of refraction of a medium is 1.4 determine the speed of light in that medium?
Speed of light in air (which has an index of refraction of 1) is 3 * 10^8 m/s. So divide the speed of light by the index of refraction of the new medium to obtain the speed of light in that medium. Hope I helped!!
