What is the difference between natural glass and synthetic glass?
No it is a man made material.Glasses are typically brittle and can be optically transparent.The most familiar type of glass is soda-lime glass, which is composed of about 75% Silicon dioxide (SiO2), sodium oxide (Na2O) from soda ash, lime (CaO), and several minor additives. The term glass is often used to refer only to this specific use

Refractive index of a glass slab using a travelling microscope?
To find the refractive index of a glass slab using a travelling microscope, you would first place the glass slab on a flat surface. Using the travelling microscope, measure the apparent shift in the position of the object when viewed through the glass slab. By knowing the thickness of the glass slab and the shift in the position, you can calculate the refractive index using the formula: Refractive index (n) = (apparent shift + 1) / actual shift.
What is glass's natural resource?
Glass is formed from sand or silica.
Is glass a natural fiber or a synthetic fiber?
Natural fibre
