When measuring the angle of incidence and the angle of refraction the imaginary line drawn perpendicular to the surface at the point of incidence is called the?
normal
If the angle of incidence increases and the indexes of refraction stay the same what happens to the angle of refraction?
The angle if refraction also increases.
Describe an experiment to find the refractive index of a glass block?
You can investigate fraction in glass using a rectangular glass block. By tracing the rays of light on a piece of paper, you can measure the angles of incidence (i) and refraction (r). If you repeat this process for a range of different angles of incidence, you would find that the sine of the angle of incidence and the sine of the angle of refraction are constant. This ratio is called the refractive index of the material, and is given the letter n.The angles of incidence and refraction are related by the following equation:sin in=__________sin r
What does a prism do with white light?
A prism can help us understand the refraction and the reflection of light when it asses between 2 different mediums ( from one medium into another less refractive or from one medium into another more refractive ) and the ray of light may emerge out of the prism by refraction or by reflection and sometimes by total internal reflection ( by obeying the 2 laws of reflection and by making the angel of incidence equal to the angle of reflection ) and sometimes it may continue its path without deviation that is when the angle of incidence is equal to 0 degrees then the angle of refraction will be equal to 0 degrees this is called undeviated !It separates the wavelengths contained in a beam of light.
When incident angle is equal to critical angle then angle of refraction will be what?
When the angle of incidence equals the critical angle, there is no refraction wave as we usually understand it. The result is a surface wave. Let us suppose we are asking about light incident on a flat interface between to mediums which are transparent (nonabsorbing). The formula for the angle of refraction says the angle of refraction approaches 90 degrees, so the direction the wave would be traveling would be parallel to the interface. The same formulas in electromagnetic theory will also predict that the energy transmitted across the surface decreases to zero as the angle of incidence increases towards the critical angle. That is the equivalent to the more common statement that there is total internal refection. Advanced mathematical treatments of this topic show that the electromagnetic field does exist on the transmission side of the interface and that energy is flowing parallel to the interface in that region. That is the surface wave. The energy in the surface wave decays exponentially with distance from the interface into the transmission region.
Does the index of refraction equal the angle of refraction?
Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index
When measuring the angle of incidence and the angle of refraction the imaginary line perpendicular to the surface at the point of incidence is called the?
normal
Does doubling the angle of incidence cause the angle of refraction to double?
No, doubling the angle of incidence itself will not cause a doubling of the angle of refraction.

normal.
If angle of incidence equals critical angle what is angle of refraction?
If the angle of incidence equals the critical angle, the angle of refraction would be 90 degrees. This occurs when light travels from a denser medium to a less dense medium and undergoes total internal reflection.
How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?
Angle of refraction will be less compared to the angle of incidence in this case.
What is the relationship between the angle of incidence and the angle of of refraction known as?
The COEFFICIENT of Refraction.
How do you compare the angle of incidence and the angle refraction?
The angle of incidence is the angle between the incident ray and the normal to the surface, while the angle of refraction is the angle between the refracted ray and the normal to the surface. These angles are related by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media the light is traveling through.
