If a beam of light enters a substance with a higher density than air and at an angle, the light is refracted so that an object on the far side of the substance appears to be closer to the observer. If the density of the substance is lower than that of air, the light is refracted away from the observer and the object being viewed appears to be farther away.

∙ 15y agoWell the angle of refraction of light depends on refractive index of medium. You can calculate angle of refraction if you know the value of refractive index of medium. Suppose n is value of refractive index, i is ngle of incidence, r is angle of refraction then: sin(r)=sin(i)/n

∙ 7y agoWhen light travels from a medium with high refractive index to one with a lower refractive index, the ray bends away from the normal. If the incident ray arrives at close to tangential to the surface, the refracted ray may be refracted back into the medium with the higher refractive index. This is called total internal refraction and is a form of reflection.

How does the angle of incidence compared with the angle of refraction for sound?
For refraction, the general relationship is given by Snell's Law.
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
Does the angel of refraction depend on the wavelength?
Yes, the angle of refraction depend upon the wavelength.
How is refraction of light related to wave length of colors?
The longer the wavelength, the greater the angle of refraction.
Are angle of incidence and angle of refraction proportional?
Yes. The proportionality constant is ' 1 '.
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.
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 angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
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
The refractive index of water is 1.33 a ray is incident from water on air at an angle of incidence equal to 30 degree what is the angle of refraction in air?
nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees
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.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Q: How do you think increasing a medium's index of refraction might affect the angle of refraction?
If angle of incidence equals critical angle what is angle of refraction?
90o. i think there will be no refraction there will be totally internal reflection
Is the angle of refraction the same as the angle of reflection?
No.
Is refraction angle equal to the angle of reflection?
No.
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.
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
