Explanation:
It is given that,
Refractive index of zircon, n = 1.923
The wavelength of visible light ranging from 380 nm to 760 nm in a vacuum.
Wavelength 1, ![\lambda_1=380\ nm=380\times 10^{-9}\ m](https://tex.z-dn.net/?f=%5Clambda_1%3D380%5C%20nm%3D380%5Ctimes%2010%5E%7B-9%7D%5C%20m)
Wavelength 2, ![\lambda_2=760\ nm=760\times 10^{-9}\ m](https://tex.z-dn.net/?f=%5Clambda_2%3D760%5C%20nm%3D760%5Ctimes%2010%5E%7B-9%7D%5C%20m)
We need to find the shortest and longest wavelength. For shortest wavelength, ![\lambda_s=\dfrac{\lambda_1}{n}](https://tex.z-dn.net/?f=%5Clambda_s%3D%5Cdfrac%7B%5Clambda_1%7D%7Bn%7D)
![\lambda_s=\dfrac{380\times 10^{-9}}{1.923}=1.97\times 10^{-7}\ m](https://tex.z-dn.net/?f=%5Clambda_s%3D%5Cdfrac%7B380%5Ctimes%2010%5E%7B-9%7D%7D%7B1.923%7D%3D1.97%5Ctimes%2010%5E%7B-7%7D%5C%20m)
For longest wavelength, ![\lambda_l=\dfrac{\lambda_2}{n}](https://tex.z-dn.net/?f=%5Clambda_l%3D%5Cdfrac%7B%5Clambda_2%7D%7Bn%7D)
![\lambda_l=\dfrac{760\times 10^{-9}}{1.923}=3.95\times 10^{-7}\ m](https://tex.z-dn.net/?f=%5Clambda_l%3D%5Cdfrac%7B760%5Ctimes%2010%5E%7B-9%7D%7D%7B1.923%7D%3D3.95%5Ctimes%2010%5E%7B-7%7D%5C%20m)
Hence, this is the required solution.
Answer:

It's Scientifically proven
Opposite Poles in Magnets Attract Each-other
Answer:
Size
Explanation:
A vector is a quantity that has both a direction and magnitude.
The direction the arrow is pointing represents the direction of the vector, and how big the arrow is represents the magnitude.
You can remember this as "magnitude" means the exact same thing as size.
