Use Snell's Law.
Snell's Law is:
Sin i divided by Sin r, where "i" is the angle of incidence and 'r" is the angle of refraction.

A light ray goes from air into acrylic block is the angle of refraction larger or the angle of incidence?
The angle of refraction is larger. BOOBIES
How does the angle of incidence compare with the angle of refraction when light passes obliquely from air to glass?
same problem dude..
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
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
Why light ray does not change it path when fall prallel to the normal?
The angle of incidence would be 90 degrees, so the angle of refraction is 0 degrees, as the light ray does not deviate.
How do you compare the angle of incidence and the angle refraction?
The angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
What are the terms related to refraction of light?
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
What angle does light travel along that causes bending in refraction?
The angle of incidence.

What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
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.
What are characteristics of refraction?
1. When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...
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.
In which direction do light rays reflecting off a smooth surface reflect?
Newton: " the angle of incidence equals the angle of refraction."
How does the angle of the refraction compare with the angle of incidence in each case?
A comparison of the angle of refraction to the angle of incidence provides a good measure of the refractive ability of any given boundary. For any given angle of incidence, the angle of refraction is dependent upon the speeds of light in each of the two materials. The speed is in turn dependent upon the optical density and the index of refraction values of the two materials. There is a mathematical equation relating the angles that the light rays make with the normal to the indices (plural for index) of refraction of the two materials on each side of the boundary. This mathematical equation is known as Snell's Law
