What does the critical angle depend on?

What does the critical angle depend on?

Critical angle depends on a number of factors like refractive index and wavelength. Complete answer: When a ray of light travels from denser medium to a rarer medium such that the angle of refraction is a right angle, in this case the angle of incidence is called the critical angle.

Does the critical angle depend on the wavelength of light?

Yes, because sinC=1/μ where C is critical angle. μ depends on wavelength hence, critical angle will also depend on wavelength.

For what Colour of light does the critical angle is least?

violet colour
Critical angle is minimum for violet colour.

Is the critical angle the same for all wavelengths?

The critical angle does not depend on wavelength. Here is the equation to calculate the critical angle and wavelength is not there. However, due to dispersion, there is a small difference in refractive index at the different wavelengths. This causes the critical angle to be slightly different at different wavelengths.

On what factors does angle of deviation depends?

Ans: Following are the factors on which the angle of deviation depend on: The angle of incidence. The refracting angle of the prism. Refractive index of the material used in the prism.

How does critical angle depend on wavelength?

Critical angle is affected by the refractive index of second medium with respect to the first medium. This in turn depends on: Wavelength: Critical angle increases with increase in wavelength (least for violet). Temperature: Critical angle increases with increase in temperature.

Is critical angle depend upon the colour of light used for which colour it is maximum?

Yes, the critical angle depends on the refractive index which turns depends on the wavelength of light so critical angle depends on the color of light. The critical angle is inversely proportional to the refractive index. When it increases the critical angle then automatically increases in wavelength of the light.

Is the critical angle greater for red or violet?

Violet light is refracted most and reemerges at an angle of about 40° compared with the incident sunlight; red light is refracted least and reemerges at an angle of 42° compared with the incident sunlight.

Which has the larger critical angle red light or violet light what does this tell you about the index of refraction of red light versus violet light?

Which colour has higher critical angle red or blue?

The critical angle for ‘Red’ colour is higher.

Does the angle of minimum deviation depends on the Colour of light?

The angle of refraction depends on refractive index, so it also depends on the wavelength of light. The deviation of light through a prism depends on refraction, therefore it also depends on the wavelength of light. This is true whether the deviation is minimum or not.
