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 angle of incident?
The angle of incidence is the angle between the incident ray (incoming light ray) and the normal (perpendicular line) to the surface it strikes. It's a critical factor in determining how light or energy is reflected, refracted, or absorbed by a surface.
Is the angle of incidence the same as angle of refraction?
No, the angle of incidence is the angle between the incident ray and the normal line, while the angle of refraction is the angle between the refracted ray and the normal line. In general, these angles are not the same, except in the case of normal incidence where they are both zero.
Why can the refracted ray can also be the incident ray?
The refracted ray can coincide with the incident ray when light moves from one medium to another at a 90-degree angle relative to the boundary between the two media. This scenario leads to no bending of the light ray, resulting in the refracted ray following the same path as the incident ray.
What is the angle of refraction?
the angle between the refracted ray and the normal
What is refractive angle?
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
What is the angle between refracted ray and the normal?
The angle between the refracted ray and the normal is called the angle of refraction. It is measured from the normal to the refracted ray inside a medium due to the bending of light as it passes through different mediums.
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
what is the angle between the incident ray and the normal are called?
The angle between the incident ray and the normal is called the angle of incidence.
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.
Prove that the angle between reflected and refracted rays is 90 degree if a ray incident from denser to rarer medium?
When a ray of light travels from a denser medium to a rarer medium, the angle of refraction is greater than the angle of incidence. The reflected ray and the refracted ray lie in the same plane as the incident ray. Using Snell's Law and the principle of reflection, we can show that the sum of the angles formed by the refracted and reflected rays with the normal is equal to 90 degrees.
