Uses of total internal reflection?
Total Internal Reflection is an optical phenomenon which occurs when a ray of light strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary, no light can pass through and all of the light is reflected. The critical angle is the angle of incidence above which the total internal reflection occurs. Hope I helped!
What is the angle between lines of force and equipotential lines in an electrical field?
The angle is a right angle.
What is the difference between phase angle and phase difference?
Although we use the term 'Phase angle' it's also an angle referred to another phasor (voltage or current).For example,conventionally when expressing power factor, we use 'voltage' as the reference. So the 'phase angle' of a particular phasor is the phase difference between our reference (voltage) & the phasor.As the gist, both mean the same except that 'phase angle' is the direction of the phasor w.r.t. positive x direction (reference)..AnswerBy definition, phase angle is the angle by which a load current leads or lags a supply voltage.Phase difference is the angle between any two electical quantities -for example, the angle two phase voltages of a three-phase system.

How it can be proved that angle between two straight lines is equal to the angle between their normals?
If two lines have angles theta1 and theta2 relative to some third arbitrary line, then the angle between those two lines is theta1 minus theta2. The normal of a line at a point is a line that is 90 degrees from the line going through that point, so the angle between a line and its normal is 90 degrees. As a result, the angle between the two normals of those lines is (theta1 plus 90) minus (theta2 plus 90), which is the same as theta1 minus theta2 because the two plus 90's cancel each other.
What is the correct definition of the angle of deviation?
it is the angle between the direction of the incident ray and the refracted ray.
What is the angle between refracted ray and the normal?
Angle of refraction
What is refractive angle?
the angle between the refracted ray and the normal
What is the angle of refraction?
the angle between the refracted ray and the normal
What does the term angle of deviation mean in reference to light?
the angle the theoretical incident ray makes with the final refracted ray
How does incident light emerge from a prism?
Incident light hits a prism, refracted or reflected light emerges from it. In what manner it is different from the incident light depends on the angle of incidence and the angles of the prism. Commonly it may be refracted, dispersed or reflected back.
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
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
Is optic fiber an application of refraction?
yes it is. when a light is incident on one end of fiber at a small angle it is refracted into the fiber.
Prove that the angle between reflected and refracted rays is 90 degree if a ray incident from denser to rarer medium?
Rephrase the question PLEASE. I can't even prove there is a question in that sentence.
When light is incident on a surface at 30 degrees it is found that reflected ray and refracted ray are perpendicular to each other Find angle of refraction How?
The angle of incidence equals the angle of reflection.
Why does light that is normal to a refracting surface not get refracted?
Because the angle of refraction depends (among other things) on the difference between the angle of incidence and the normal. Therefore, if if the angle of incidence is equal to 90 degrees (normal), then the angle of refraction is zero. This is the reason why images, when viewed straight-on through a window, do not appear distorted. Or, think about it like this: If light was refracted when normally incident, which way would it refract?
