Question

To compare the refractive index of two transparent liquids using a concave mirror and a single pin

Answer 1

• Aim is to find the refractive index of a) water, b) coconut oil using a plane mirror, and an equiconvex lens made of glass and an adjustable object needle.The theory behind liquid lens is based on the properties of one or more liquids to create magnifications within a small amount of space.The focus of a liquid lens is controlled by the surface of the liquid .Water normally forms a bubble shape when adhered to materials such as glass.
