Lenses operate on having another index than the immediate surrounding. Sink a lens in a media with the same index and it won't work. It'll be like it's all glass.
Everything a lens does is the result of the change of refractive index at its surface.If the lens is surrounded by a medium with the same refractive index as the glass,then there is no refraction (bending) of light at the glass surface, and the lens is nolonger a lens. If you could find such a liquid, you might not even be able to see thatthere's a lens down there in it.
The minimum value of the refractive index is 1, which corresponds to a vacuum. The refractive index of a medium is always greater than or equal to 1.
There is no relationship between miles (measure of length) and gallons ( measure of liquid volume.)
Yes they are equal in length
You cant meaure this because liters is a way of measuring liquid and meters is a way of measuring length
You can't do this conversion because these are unequal base units one measures liquid and one measures length
A Square has four equal length sides
A square has four sides of equal length!
The answer depends on which aspect of a rhombus. Its sides are of equal length but its diagonals are NOT!
4 sides of equal length.
A square (a by a) and a rectangle (a by b) can have sides that are of equal length.
