Define critical angle?
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
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
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
Why perpendicular light rays don't refrect through a medium?
As it is parallel to the normal to the surface, the angle of incidence is zero and hence the angle of refraction also has to be zero. Hence no deviation and no 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
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.
Angle of refraction is less than 90 degree true or false?
False. You can have total internal reflection where the effective angle is greater than 90 deg
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.
