Updated: 11/3/2022

You can use Snell's Law. Note that you need two angles for this - the incoming angle, and the outgoing angle.

How do you work out the angle of incidence and refraction?

Both can be calculated easily using Snell's Law, which you can find easily online. However to use Snell's law you will need one of the angle of incidence or refraction as well as the refractive index of the media the light ray passes through

How do you work out exterior angle for a triangle?

It is: 180-interior angle = exterior angle

When does angle-side-side in geometry work?

When the angle is 90 degrees.

At what angle Work is minimum?

Work is minimized when the angle between the force applied and the direction of motion is 90 degrees (or π/2 radians). At this angle, the force does not contribute to the displacement in the direction of the force, resulting in zero work done. In general, as the angle increases from 0 to 90 degrees, the work done decreases, reaching its minimum at 90 degrees.

How do you work out the length of a rectangle with the width and an angle?

It depends on what angle. The main angles of a rectangle are all 90 degrees and knowing that does not help. If however, the angle in question is the angle made by the diagonal with one of the sides, then it is possible to use a basic trigonometric ratio to work out the length. Details will depend on which angle is given.

At what angle does no refraction occur?

No refraction occurs when light travels perpendicular to the interface between two different media, resulting in an angle of incidence of 0 degrees. This is known as the normal incident angle.

How do you work out the angle of incidence and refraction?

Both can be calculated easily using Snell's Law, which you can find easily online. However to use Snell's law you will need one of the angle of incidence or refraction as well as the refractive index of the media the light ray passes through

What is the angle between a reflected and a refracted rays when a light ray is incident at 30 degrees on a parallel block of thickness 5cm and refractive index 1.5?

Light will be reflected at an angle of 30deg from the normal. We can work out the angle of refraction using the formula: n(1) sin(incident angle) = n(2) sin(refracted angle) We will assume the refractive index given is the relative refractive index n(2)/n(1). So sin(30)/1.5 = sin(r) r = 19.5 deg As the reflectedd and refracted rys are on the same side of the normal we can subtract them from 180 to get the angle between them: 180 - 19.5 - 30 = 130.5

How does a refractometer work to measure the refractive index of a substance?

A refractometer works by measuring how much a substance bends light. When light passes through the substance, the refractometer calculates the angle at which the light is bent, which is used to determine the substance's refractive index.

Is the law of refraction the same for light rays going in either direction between two media?

Yes, the law of refraction still applies regardless of the direction of the light rays. It states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media.

If the speed of light was the same in all materials would a lens cause light rays to bend?

No. Without refraction at a boundary between media with different refractive indices, lenses wouldn't work. The only way we would have of forming real images would be with curved mirrors.

How do refractometers work and what is their primary function in scientific measurements?

Refractometers work by measuring how light bends as it passes through a substance, which is called refraction. Their primary function in scientific measurements is to determine the refractive index of a substance, which can help identify and analyze different materials based on how they interact with light.

Why did Adolph Fick invent contact lens?

His work was based on early work, showing in theory how a lens with an appropriate curvature and refractive index could be overlaid on the cornea to provide refractive correction.

How do you use the lensometer or lens clock for finding the refractive index of a lens?

To find the refractive index of a lens using a lensometer (or lens clock), place the lens in the machine with its convex side facing up. Look through the eyepiece and focus until the crosshairs are sharp. Take note of the position of the index line on the scale. Then, flip the lens and repeat the process. The refractive index can be calculated using the formula: Refractive index = (n2 - n1) / (1 - (t * (n2 - n1))) where n1 is the refractive index of air, n2 is the refractive index of the lens material, and t is the thickness of the lens.

How does an RID detector work for HPLC?

An RID (Refractive Index Detector) for HPLC works by measuring changes in refractive index caused by the presence of analytes eluting from the column. As analytes pass through the detector cell, they displace the mobile phase, causing changes in refractive index that are detected and converted into a signal. The signal is then plotted against retention time to create a chromatogram that can be used to identify and quantify analytes in the sample.

How does refraction work in water?

When light passes from air into water, its speed decreases, causing it to bend or change direction. This bending is known as refraction, and it occurs because light travels at different speeds in different materials. The amount of refraction depends on the difference in the refractive indices of the two materials.

How does refractometer works?
