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
Is the angle of incidence is greater than the angle of refraction when light passes from a less dense to denser medium?
If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
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.
When a ray of light passes from air to glass for what angle of incidence the ray will not be deviated?
Angle of incidence has to be 0. This means that the ray has to hit normally on the surface of separation of two media
If light passes through a medium at a speed of 2.5 x 10 to the 8 power meter per second what is its index of refraction?
my answer is 5
Why the ray of light does not bend when it passes perpendicularly from rarer medium to denser medium?
Since the angle of incidence is 0, there is no chance of refraction and so the angle of refraction too becomes 0.
When a beam of light passes at an oblique angle into a material of lower optical densitythe angle of incidence is?
greater than the angle of refraction
When a beam of light passes at an oblique angle into a material of lower optical density the angle if incidence is what?
less than the angle of refraction.

Why ray does not refract when it passes through optical centre?
It does. But when the ray arrives perpendicular to the boundary, the angle of incidence and the angle of refraction are both zero, so its direction doesn't change.
When there is no refraction of light and why does it happen?
There will be refraction when light passes from one substance to the other (for example, from air to water), when the two substances have different indices of refraction, and when light passes the surface at an angle. In other cases, there is no refraction.
What is it called when a seismic wave bends as it passes from liquid to solid rock.?
it is called refraction
State the relationship between the amount of bending and the index of refraction as light passes from an optically less dense medium to an optically denser one?
The amount of bending that a light ray experiences can be expressed in terms of the angle of refraction (more accurately, by the difference between the angle of refraction and the angle of incidence). A ray of light may approach the boundary at an angle of incidence of 45-degrees and bend towards the normal. If the medium into which it enters causes a small amount of refraction, then the angle of refraction might be a value of about 42-degrees. On the other hand if the medium into which the light enters causes a large amount of refraction, the angle of refraction might be 22-degrees. (These values are merely arbitrarily chosen values to illustrate a point.) The diagram below depicts a ray of light approaching three different boundaries at an angle of incidence of 45-degrees. The refractive medium is different in each case, causing different amounts of refraction.

refraction
What is the index of refraction of a material if the angle of incidence in air is 50 degrees and the angle of refraction in the material is 40 degrees?
When a ray of light passes from material 1 to material 2: N1 sin θ1 = N2 sin θ2 where N1 & N2 are the refractive indices of the materials, and θ1 is the angle of incidence, θ2 the angle of refraction. From air to the material: N1 = 1.00, θ1 = 40°, θ2 = 50°, N2 = unknown, the index of refraction of the material: → 1.00 x sin 50° = N2 x sin 40° → N2 = 1.00 x sin 50° ÷ sin 40° → N2 ≈ 1.1917 (the index of refraction of the material)
What does light bend when it passes from air into glass?
