What is the critical angle of benzene?
42^∘
Determine the refractive index of benzene if the critical angle is 42^∘
What is the refractive index of benzene if the critical angle?
Solution: Let the critical angle be C and refractive index be μ. According to Snell’s Law, C=sin −1 ( μ1 )⟹42 ∘ =sin −1 ( μ1 )⟹sin(42 ∘ ) μ= 0.671=1.49is the required refractive index of benzene.
How do you find critical angle with refractive index?
The critical angle can be calculated by taking the inverse-sine of the ratio of the indices of refraction. The ratio of nr/ni is a value less than 1.0.
What is critical angle formula?
The critical angle = the inverse function of the sine (refraction index / incident index). We have: θcrit = The critical angle. nr = refraction index.
What is the index of benzene?
So the refractive index of benzene is 1.49.
What is refractive index of benzene?
How do you find the critical value?
In statistics, critical value is the measurement statisticians use to calculate the margin of error within a set of data and is expressed as: Critical probability (p*) = 1 – (Alpha / 2), where Alpha is equal to 1 – (the confidence level / 100).
What is critical angle in physics class 10?
The critical angle of a medium can be defined as the angle of incidence of a light ray in the denser medium which is such that the angle of refraction obtained is equal to 90∘.

What is the angle of critical angle?
90°
The critical angle is the angle of incidence, for which the angle of refraction is 90°. If light enters a denser medium from a comparatively rarer medium, then the direction of light changes and the light ray bends towards the normal.
What is the critical angle of diamond?
24.4º
The critical angle for a diamond-to-air surface is only 24.4º, and so when light enters a diamond, it has trouble getting back out.
What is the absolute index of refractive index of benzene?
The absolute refractive index of benzene is 1.5. What is it critical angle? n → Absolute Refractive index of benzene =1.5 Originally Answered: The refractive index of benzene is 1.5. What is the critical angle of benzene?
What is the refractive index of light?
The refractive index is also known as the index of refraction. It is the measure of the bending of a ray of light when it passes from one medium to another. It is also defined as the ratio of the speed of light in a vacuum to the speed of light in a given media.
What is the sine of the critical angle of a glass?
In this case the “refractive medium” is air and the “incident medium” is glass. The refractive index of air is about 1 (almost exactly). So, in this case, the sine of the critical angle is 1 divided by 1.5 = 0.6667. You will find the answer, from sine tables, to be approximately 41.81 degrees.
What is the critical angle of the air in degrees?
Using a better value for refractive index of air, I get the critical angle to be about 41.825 degrees. However that answer probably has too many decimal places.The refractive index (1.5) is given with only 2 significant figures (or significant digits). So, my final answer is “42 degrees, approximately” because that answer has 2 significant figures.
